Empty Box Problems Subtraction
6 - 3 = 3 If you start on 6 and jump back 3 spaces you land on
= 6 If you start on 11 and jump back 5 spaces you land on
6 - 2 = 4 You need to go back 2 jumps on the number track to get from 6 to
8 - 3 = 5 You need to go back 3 jumps on the number track to get from 8 to
= 10 You need to go back 4 jumps on the number track to get from 14 to
9 - 4 = 5 You have to start on 5 (the total) and move forward 4 jumps to work out the starting number
= 8 You have to start on 8 (the total) and move forward 5 jumps to work out the starting number
Now try these… = = = = = = 2
Combining Like Terms. Only combine terms that are exactly the same!! Whats the same mean? –If numbers have a variable, then you can combine only ones.
BALANCING 2 AIM: To solve equations with variables on both sides.
SUBTRACTING INTEGERS 1. CHANGE THE SUBTRACTION SIGN TO ADDITION 2. TAKE THE INVERSE OF THE SECOND NUMBER 3. FOLLOW THE RULES FOR ADDITION 4. ADD THE OPPOSITE.
SYSTEMS OF EQUATIONS. Substitution Method Ex. 1:2x + y = 15 y = 3x We have been using the Substitution Property in our proofs. Now we are going to use.
Test B, 100 Subtraction Facts
BALANCING EQUATIONS AIM: Solve equations with variables on both sides.
1. Solve equations with variables on both sides. 2.Solve equations containing grouping symbols. GPS M7A1, M7A2, M7N1 ~ PEARSON Objectives The student will.
Dividing Monomials. For all integers m and n and any nonzero number a …… When the problems look like this, and the bases are the same, you will subtract.
Multiplying binomials You will have 20 seconds to answer each of the following multiplication problems. If you get hung up, go to the next problem when.
