*Question 1: (-7) - (-4)*Owe 7 remove Owe 4.

Standard Form: -7 - (-4) = -3

Take out the brackets, but leave the brackets in the -4, because it separates the subtraction sign from the negative sign.

*Put the answer back into the standard form question, after you have modelled it.*

*Question 2: (+1) - (-2)*

*Have 1 remove Owe 2.*

Standard Form: 1 - (-2) = 3

Take out the positive sign in the 1 because it is redundant.

*Redundant- You don't need it there.

*Put the answer back into the standard form question, after you have modelled it.*

*Question 3: (-3) - (+7)*

*Owe 3 remove Have 7.*

Standard Form: -3 - 7 =

Take out the brackets on both integers. Also take out the positive sign in +7, because the (+) is redundant. The brackets are also redundant, it's not needed.

*Put the answer back into the standard form question, after you have modelled it.*

*Here's a link for you to practice subtracting/removing integers!*

*Here's a video to help you, if you still don't get it.*
I like how you explained what redundant is. I also like how you showed your work and had pictures, you made everything a lot easier to understand. I also like how you have a good video and a link. Good Job!
