you would round 762 to 800, then you would round 332 to 300. You would take those 2 numbers and put them in the questions and it should look like this: 800-300, then you would subtract Good luck!
alright mate. First off, you're in elementary... get off your technology and learn you something. Reguardless- Round 762 down to 760 and 332 down to 330. now use mental math to do 760-330 and you'll get 430.
