What a view Week 2

What a View!

What a view is a level 3 strategy book that lets you use the most knowledge you can think of. This figure it out book taught me how to use a lot more than one strategy for one question.The next thing that I would like to learn is to use square roots in maths equations.

The strategie
What strategy I've worked on?
Ill give an example on one equation I have used.
13 x 17 = 221
(10 x 10 =100
10 x 3 =30
10 x 7 =70
3 x 7 =21   )
And my other strategy i've used is here.
13 x 17 = 221
(13x10=130
13x7=91
130+91=221

I have been learning many more examples for this term, for advanced learning, I would like to learn about coordinates.
