## miranda090701 one year ago Use number properties to simplify the following expression. -5 + (5 + 3) In the box below, show each step in simplifying the expression and explain which property you used in each step.

1. SolomonZelman

i don't even know how to start :::::

2. SolomonZelman

Parenthesis first

3. SolomonZelman

$$\Huge\color{blue}{ \displaystyle \rm P }$$arenthesis $$\Huge\color{green}{ \displaystyle \rm E }$$xponents $$\Huge\color{orangered}{ \displaystyle \rm M }$$ultiply $$\Huge\color{orangered}{ \displaystyle \rm D }$$ivide $$\Huge\color{darkgoldenrod}{ \displaystyle \rm A }$$dd $$\Huge\color{darkgoldenrod}{ \displaystyle \rm S }$$ubtract

4. SolomonZelman

this is the abbreviation for the order of operations....

5. SolomonZelman

So first you do the "5+3" in the parenthesis, what is 5+3?

6. miranda090701

It's talking about the properties not operation

7. SolomonZelman

well, you say say $$\large\color{black}{-5+(\color{red}{5+3})~~~\Rightarrow~~~\underline{-5+5}+3 }$$ ( $$\large\color{black}{\Uparrow }$$ you do this first)

8. SolomonZelman

same as -b+(b-a) = -b+b +a=0+a=a

9. miranda090701

okay
