can someone explain to me how to use "squared"? I do 2+2 and its four. but when I do 3+3 and I get 6, my brother tells me that's not squared. can you help me out?

Answers

Yes. You've come to the right place. I can help. To "square" a number means to MULTIPLY it by itself . . . NOT add it to itself. '2' is the ONLY number that gives the same result both ways. The square of 3 is 3 times 3 = 9 . The square of 6 is (6 times 6) = 36.

Answer:

$36

Step-by-step explanation:

Since 30% = 30/100 then we can transform it into a decimal:

30%=0.30

Now if we multiply 120•0.30, we will get how much we saved.

$36, we saved $36.

Bonus information:

If the problem was to say "How much does the cell phone cost after the discount?", then you would multiply 120•0.70.
