Again, multiplication takes precedence...

1-3*4+7 = 1-12+7 = -4...

>> No.1872947

1-3x4+7

1-12x+7

-12x+7

x+7=12

x=4

>> No.1872961

1-3X4+7=0
1-12x+7=0
8=12x
8/12=x
x=0.6...

>> No.1872968

What you are doing is "OH BEDMAS LOL" 3x4= 12, now I have to add 7 and subtract 1. That gives me 18 right?
Failure.
1-(3x4)+7
1-12+7
-11+7
-4

PEMDAS answer is 18

>> No.1873006 [DELETED] 

PEMDAS

MD are equally weighed as are AS. Multiplication doesn't have priority over division; it all depends which comes first. May attention in elementary school you idiots.

multiplication is before addition
1-3x4+7
1-12+7
-11+7
-4

>> No.1873047

Parenthesis, exponents, Multiplication/Division, and Addition/Subtraction. You do whichever of the two comes first left-to-right. So it would be:

3 x 4 = 12

1 - 12 = (-11)

-11 + 7 = (-4)
