sign doesn't change. The 2nd integer's sign becomes opposite and so does the addition/multiplication/subtraction/division sign which in this case is subtraction, so now it's an addition statement.

3 + 10 = 13.

Standard form: +3 - -10

+ 3 - (-10)= +13

One negative integer plus one positive integer = Zero. For this question, I took 5 away from 8 and I got 3. I knew I owed more and so, I put a negative sign before 3.

Standard form: -8 + +5

-8+5= -3

The equivalent statement for this question is (-3) + (-3). The 1st integer didn't change but the subtraction sign and 2nd integer did.

Standard form: -3 - +3

-3 - 3= -6

The equivalent statement is (+10) + (+5) = (+15)

Only the subtraction sign and the 2nd integer changed.

Standard form: +10 - -5

+10 - (-5) = +15

For this one, I just subtracted 6 from 9 and got 3. I knew I had more and so, I added a positive sign before 3.

Great Work Patricia! Your pictures were very clear to understand. I like how you put an explanation beside each one of your pictures. Overall, good job and keep up the good work!
