Algebra 3

Accomplishable Algebra
We are learning to identify the rule for a pattern of numbers

Multiplication practice:

56 ➗ 8 = 7        72 ➗ 9 = 8     44 ➗ 11 =4
45 ➗ 9 = 5             64 ➗ 8 = 8 56 ➗ 7 =8
35 ➗ 5 =  7 144 ➗ 12 = 12         27 ➗ 3 =9
82 = 64                 92 = 81                    72 =     49      
62 =     36

Finding the rule:
What are the next numbers in the pattern? What is the rule for the pattern?
