Multiple Choice
This week, we are subtracting, which we change to addition. "Add a line and change the sign."
When we change the problem 8 - 10 = ?, it becomes_________

For 8-10=
1) First number stays the same.
2) Add a line (change to addition)
5
3) Change the sign of the second number to its opposite. 10 becomes -10.
4) Add using the rules from last week, or number line
So 8 + -10 = -2 the signs are different, so find their difference and keep it negative.
