That is, can you square the number 35? There's a mental math trick so that you can easily square any number ending in 5. Here's how the trick works.Look at the first digit of 35, which is the number 3. We add one to that number, 4, and then multiply those two numbers together. So we have 3x4 = 12, and these are the leading digits of the answer. Now we just write 25 as the last two digits, so we get 1225. And that's it! We have calculated 35 squared is 1,225 in an amazingly simple way! Math does not have to be hard.
