L.I. I am learning to solve multiplication problems with powers
We have already looked at exponents, today we are going to quickly refresh our learning on exponents and build some more learning.
Cool, right. Lets quickly do this work to show you understand and then I want you to watch this video about adding and subtracting exponents.
Exponent Rules Part 1: Introduction to exponent rules
L.I. I am learning to solve multiplication problems involving positive and negative numbers(integers)
We have looked at some of these problems before, in add/sub. There were learned that.
(Positive × Positive = Positive) + x + = + +2 x +2=+4
(Positive × Negative = Negative) + x - = - +2 x -2 = -4
(Negative × Positive = Negative) - x + = - -2 x +2 = -4
(Negative x Negative= Positive) - x - = + -2 x -2 = +4
- because two negatives cancel each other out.
(Write this in your book, it will help - also highlight it)
Okay lets watch this video

L.I. I am learning to solve division problems using reversals
Hint, use a calculator!
For number one, do you see how the answer has been reversed and pulled back across the equals sign? So by dividing 14.79 by 4.721 you get 3.13 which is the answer to the missing blank. Again, using our knowledge of equivalency , 3.13x 4.721 = 14.79
You will need to write the questions into your books
