• Don't Miss: 8 Ways Google Lens Can Help You Be More Productive

Step 1: Access Google Lens

There are multiple ways to access this feature, but here's the best one. Open the Google Assistant by long-pressing your home button or swiping inward from one of the bottom corners. From there, press the Google Lens icon (to the left of the mic icon) and grant access to your camera if prompted.

If you have a Pixel smartphone, then Google Lens is built into your Camera app. When you open the Camera, tap More to access the additional camera features, where you'll find Lens.

Step 2: Enter Homework Mode

With Lens open, you'll notice that the camera view is constantly scanning what it sees. But, for the purpose of solving math problems, you'll want to select Homework mode from the ribbon menu at the bottom.

Step 3: Scan the Equation

Center the target brackets over the equation until Lens recognizes it and highlights it on the screen. Tap the equation, and Lens will analyze it. Lens can recognized typed or hand-written equations, though legibility can handicap the app's abilities for the latter.

Step 4: Solve & Learn

For simpler equations, Google will provide the steps to solve the problem as well as the solution. For more complex functions, Google will punt to other services from the web, such as Cymath, MathPapa, and Wolfram|Alpha.

You can also scroll further to find other resources, such as flashcards for similar problems from Quizlet and key concept explanations. Homework mode isn't as helpful for solving word problems, however, the hive mind of Google does provide resources from across the web for these exercises as well.

A calculator is a handy tool for solving math problems, but it can sometimes be a pain to type the equation. Google Lens can solve a problem simply by taking a photo. We'll show you how to use the feature.

Android devices can access Google Lens in a couple of different ways, depending on your phone. However, the universal method that works for Android , iPhone , and iPad is through the Google app.

Of course, the first thing you'll need is a math problem to solve. Google Lens can solve simple equations such as "5+2" or more complex formulas such as "x 2  - 3x + 2." You can scan the problem from a real-world piece of paper or from a digital display.

Open the "Google" app on your  Android  phone or tablet, iPhone , or  iPad . Tap the "Lens" icon from the right side of the search bar.

Next, swipe over to "Homework" in the bottom toolbar.

Point your device's camera at the math problem you want to solve, making sure the problem is inside the frame. Tap the "Shutter" button.

First, double-check that the question at the top of the card is correct. You can tap "Steps to Solve" to see the steps that were taken to get to the solution. The solution is shown at the bottom.

To scan a different problem from the same photo, tap the "T" icon above the solution card.

Next, tap the next solution you'd like to solve.

The solution will appear in the card below again.

If the Google response is not adequate or it can't find a solution, you can pull up on the card to reveal the full Google Search results with solutions from other sources.

That's it! Hopefully, you'll be able to find solutions to all your problems.

Google Will Solve Your Kids' Math Homework. That's a Good Thing.

Here's the perfect tool for the homeschooling era.

• Google's Socratic is checking your kids' math homework , and that's a good thing.
• The tool is powered by optical character recognition (OCR), which uses scanning and artificial intelligence.
• The ability to check work is a gamechanger for families facing emergency homeschooling.

Google has announced a new technology, powered by an acquisition called Socratic, that will let students take photos of their math homework in order to get the solutions. Google says it wants the Lens-powered technology to help parents and caretakers who are homeschooling, likely for the first time, as a result of the global COVID-19 pandemic.

Google's search engine is already crammed with autosuggestions that you can tell are seeking homework answers. When you search for a classic novel, the related searches are always things like “Darcy house name” or “Meaning of dance scene.” Math is harder to Google because of the array of symbols the average person doesn’t know how to type, and people’s math anxiety to begin with makes it more difficult to measuredly seek out what they need.

➡ You love numbers. So do we. Let's nerd out over numbers together.

The specific Google Lens integration doesn’t have a set release date, but Socratic is already available for people to download and use. Using Socratic, students can examine a variety of different subjects, but the robust math functionality really stands out—and took six more months to develop . The app uses artificial intelligence to recommend more and more relevant resources and tutorials to students.

Socratic uses optical character recognition (OCR), whose scope begins with simple scanning of documents using letter “patterns.” Older OCR users may remember the days when “cl” often became “d,” for example, and cheaper or more primitive OCR can still conflate characters this way. More advanced OCR began to consider the same factors as spellcheck or grammar check, using context of entire words or phrases.

Several layers of functionality are happening when a photograph of handwritten math homework is turned into a solution or a resource list. Without peeking behind the scenes of Socratic in particular, we can still explore what’s going on using generalized logic from computing and programming.

First, the OCR is turning handwriting into digitized content—that means addressing a squashed or tilted addition sign, for example, and recognizing that the common “x” used for multiplication by lower level math students is an operator, not a letter or algebra “x.” Then the software must store each part of the mathematical phrase as a separate variable that can be acted on.

In many languages, numbers are “primitive” variables, to use the programming term. Basically, the number can be directly stored as itself without requiring an intermediary bookmark, compared with what’s next: storing the idea of an addition operator. (This is very simplified, and some languages choose to store numbers another way. Large numbers are also handled differently from small ones.)

📩 Make your inbox more awesome.

Once all the pieces are considered separate and usable, the programming must do the intended math to get the correct answer and compare that back to what your photograph actually depicts. Even calculators have surprising computing ability in the form of things like order of operations, but for a long time this was not a given. Today, the absolute cheapest calculator you can buy can do square roots and even store values for you .

If you can't believe Google will just do your kids' homework for them, then you haven't been paying attention to how children have used Google for at least 15 years, let alone graphing calculators that have had capacity to solve at least some functions since 1998 . But adding robust technique and tutorial support is a great new angle that should hopefully help parents and tutors feel empowered to walk kids through any math problems they encounter.
