I dont get adding and subtracting negative & positive numbers.
Alekssandra [29.7K]

Answer:

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

<em>-2</em> is<em> 2 less then 0.</em>

<em>4 </em>is <em>4 more then 0</em>

So, in the equation 4 + (-2), you start at <em>4</em> then go <u>left</u> on a number line <u>twice</u>.

4+(-2) = 2

The same goes for -2 + 4, start at <em>-2 </em>on a number line and go <u>right</u> 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
