How do I solve the equation 7+7÷7+7×7-7? I got 0. I put parentheses around the (7+7) which is 14 then (7+7) which is 14. 14÷14 is 1 then 7-7 is 0. 1×0 is 0. Not sure if this is right.

Sagot :

You use PEMDAS or in some areas GEMDAS
Since there are no parenthesis set in place and no exponents we do (Multiplication or division first) whichever comes first. In this case it's division
7/7= 1 so your equation is now 7+(1)+7x7-7
Next you do multiplication which is 7*7 which is 49
7+(1)+49-7
Now you add or subtract whichever comes first
7+1 = 8
8+49-7
49+8 = 57
57-7 = 50
Your answer should be 50
