Properties of Equality CA SS: 5.0

Today we went over the four properties of equality and one-step equations.  Tomorrow is two-step equations when you combine two properties.  Here is how we looked at the two ways.

 Addition/Subtraction Property of Equality has a horizontal way or vertical way.  Multiplication Property of Equality needs to be written as division and then as multiplication.  Become comfortable with those fractions.


p.116 (1-19:odd; 2 ways)
p.122 (1-15:odd; 2 ways, 17,19)

Period 4 only p.165

i didnt understand why we had to do it the hard way when we could just say that
x-3=-7
-7+3=-4
x=-4

it just makes the problems seem harder! anywhos does anyone need help with homework?

Mr. Gerson said...

You are using so many properties in one step: symmetric property, addition property, and skipping lots more. How will you identify them when we get to proofs?

A really good thing to do is what Mr. Gerson said in class, to color code your work it really helps you to understand it better
