Insert paretheses where needed in each expression to show how tp get each result.
A: 2 + -3 x 4 = -10
B: 4 + -3 x -4 = -4
C: -12 / 2 + -4 = 6 ( P.S the / means divided by)
D: 8 / -2 + -2 + -6
As usual, can you please tell me how you got the answer so that i can understand it more clearly.

A: 2 + (-3 x 4 )= -10 -3x4=-12+2=-10
B: (4 + -3) x -4 = -4 4+-3=1x-4=-4
C: -12 / (2 + -4) = 6 2+-4=-6 -12/-2=6 because same= positive and diff.= neg.
D: 8 / -2 + -2 + -6 what result am i trying to get

A: 2 + (-3 x 4) = -10
2 + -12 =10
Draw out a number line from negative to positive and add subtract on it. Like
-25 -24 -22 .......0 1 2 3 4 5......25
B: (4 + -3) x -4 = -4
Using that number line:
-5 -4 -3 -2 -1 0 1 2 3 4 5
go back 3 (to the left) from the positive 4 and get 1
1 * (-4) = -4
You do the rest

You need to understand the order of precedence. Multiplications and divisions are done before additions and subtractions. You move from left to right.
A. This one is actually okay as is. You'll get:
2 + -12 = -10
B. For this one you want to multiply -4 by 1 so:
(4 + -3) * 4 = -4
C. You want to divide -12 by -2 so:
-12/(2 + -4) = 6
D. I'm assuming that last + is actually =.
This one is okay as is: You'll divide to get -4. Add -2 and you'll get -6.

A. 2+(-3x4)=-10
B. (4+-3)x-4=-4
C.-12/(2+-4)=6
no = in D

P: parenthesis
E: exponents
M: multipulcation
D: division
A:adding
S: subtracting
follow that order for solving, so since you don't have exponents or parentheses, you just do multipulcation and division, then adding and subtracting (multipulcation and division go together, same as adding and subtracting)
example:
A: 2+ -3 x 4=-10
2+ -12= -10
-10 = -10
