By how much does 532 exceed 202?

If something exceeds something else, it’s greater than it. It goes beyond it. And so this question is asking us how much greater is 532 than 202. How much does it go beyond 202? What’s the difference between 532 and 202?

We can find the difference between these two numbers in two different ways. Firstly, we can use subtraction. We can start with 532, then subtract 202. And the amount that we’ll be left with will be the difference between the two numbers. So that method involves subtraction.

A second method involves counting on. So it’s a form of addition. This time, we’d start with 202. And we count on from it until we reached 532. And then, we’d be able to see that the amount that we’ve added on or counted on would be exactly the same as the difference between the two numbers. So both subtraction and counting on are methods that we could use to find the difference between these numbers.

Let’s use subtraction. 532 is made up of five hundreds, three tens, or 30, and two ones. And we need to subtract 202, which is two hundreds and two ones. Let’s start by subtracting the ones. Our number has two ones in it. But we need to take away two ones, one, two. If we start with two and then subtract two, we’re left with zero. The number 532 has three tens. And the number we’re subtracting 202 has zero tens. If we subtract zero tens from three tens, the number stays the same. We still have three tens.

Finally, let’s find the difference between our hundreds digits. 532 has five hundreds. And the number we’re subtracting has two hundreds. Let’s take away two hundreds, one, two. The difference between 500 and 200 is 300. And so we can say that the difference between 532 and 202 is 330. We’ve subtracted the smaller number from the larger to find the answer.

In the words of the question, 532 exceeds 202 by 330.
