Can someone actually answer this question pls its my 3rd time posting it and ill ive gotten was wrong or answers that make no se
andre [41]

Answer:

(-2+-5) equals -7.

Because the signs are the same, we dont change it.

(3+5) equals 8. Same like the other equation, the signs are the same so we do not change it.

Now we do (-7+8) The answer will be 1. Lets use a little graph since its hard to explain.

-8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8

Mark -7 anyway you want. (Circle it, draw a line under it, what ever you want.)

Now Move the line 8 times.

When you do that your line will stop at 1.

And thats how you do it.

What is 100×100?<br><br> can someone help me
Hunter-Best [27]
100 times 100
When you want to multiply 100 by 100, count up all the zeros first.
There are 2 zeros in one 100 and 4 zeros in two 100's.
Since there are 4 zeros, that means 100 • 100 is a 1 followed by 4 zeros.
This means 100 • 100 = 10,000

100 multiplied by 100 is 10,000 (ten thousand)

Hope this helps!
