Question

I dont get adding and subtracting negative & positive numbers.

Answer 1

Answer:

One way to help remember is to visualize it on a number line.

-2 is 2 less then 0.

4 is 4 more then 0

So, in the equation $4 + (-2)$, you start at 4 then go left on a number line twice.

$4+(-2) = 2$

The same goes for $-2 + 4$, start at -2 on a number line and go right 4 times.

$-2+4 = 2$

Simply, with negative numbers you go left and with positive you go right.

$-16 + (-16) = -32$

$52+(-34)=18$

When you see $[number]+(-[number])$, all that means is a positive number plus a negative number, which means a positive number minus the number that is negative as a positive. If that sounds confusing it's alright.

If you need more explanation, you can ask me in the replies
