331+193 This depends on whether you're rounding to the nearest 10 or 100. If rounding to the nearest 10, 331 rounds to 330 and 193 rounds to 190, so then you'd do 330+190. If rounding to the nearest 100, 330 rounds to 300 and 190 rounds to 200, so then you'd do 300...

The 7th square number is 49, so it has to be bigger than that.
*October 6, 2010*

**math**

It's bigger than 49, and it must be a multiple of 10 (since it doesn't end in a 5)..so your choices are 50, 60, 70, 80, 90, etc..Now check your other conditions and find your number.

Parenthesis means to do that operation first. The order of parenthesis changes the problem. Did you learn order of operations? PEMDAS. Look at the difference between these problems. (4+3)*2=7*2=14 4+(3*2)=4+6=10

False. The 3 is multiplied by 2 to get 6, and the 4 is multiplied by 3 to get 12. In order for the statement to be true, they would both have to be multiplied by the same number. 3/4=6/8=9/12
