Digit places
We occasionally see questions on SAT math asking you round up your answer to the nearest .....(tenths - thousands).
These questions should be approached in two steps.
First, you need to figure out the digit place (if tenth or hundredth).
Second, you should be careful with rounding as the numbers even after the digit place that you already figured out matter. To illustrate, a question asks you to round up your answer to the nearest thousandth. As your answer is 0.612975, you only need 3 numbers after the point (
.). As a result, you get 0.612, but wait. 0.612 is wrong here as we did not round up. The correct one is 0.613. Just be careful as College Board is really good at tossing such tricks at you.
You can see how integers and decimals differ in their digit places in the picture above. Make sure you differentiate them.
PS: I am sorry for simple language I am using. Especially, I don't want Valera reading this say "So much for my lessons and So much for my feedbacks"
