Without one, you’ll have to trust your number sense to get the right answer instead of second-guessing yourself and using a calculator for basic math. Using a calculator can actually waste a lot of time on tests if you use it as a crutch.With good number sense, you don’t have to pull out a calculator to know that 8×5=40 you just know. Practicing math without a calculator is how you develop number sense, or a good grasp of how numbers add up, multiply, divide, and break down into factors.Becoming fluent in the language of numbers is a good way to train your brain to think logically, which is a key foundation for being a good test-taker. Getting good at mental math is important for reasons that many teachers don’t really articulate: Students have heard all about why they should learn to do math without a calculator, but a lot of it boils down to, “You won’t always have a calculator in the real world!” Except it’s 2022, and we all carry whole computers in our pockets, so that doesn’t hold water anymore. Lots of students wonder, “What’s the point? Why not let test-takers use a calculator the whole time, or else not allow them at all?” The answer is that the two sections test different–but equally important–sets of skills that will serve you well throughout your college and professional career. If you take a look at the anatomy of the SAT, you’ll see that it has two math sections: one where you’re allowed to use a calculator, and one where you’re not.
