Step 1.how many times can 1 go into 3?

Step2.so you carry the 3 and subtract and you get zero.

Step 3. then you do the same with the 5.

- -117/-3
- Step 1. you line up 117 and 3. then you multiply.
- Step 2.You start from the back. 7(3) is 21.so you leave the 1 and carry the 2.
- Step 3. 1(3) is 3 plus 2 is 5. then 1(3) is 3 so you get 3. then your answer is 351.

I hope you were paying attention because now you have a quiz .there is no help on this. GOOD LUCK
