Okay then

# The MatHS Team Collab!

I want to give ideas for projects! Can I have the password incase I rejoin HS again?

**HappyDolphin**#124

Could we do some math challenges, like pre-algebra for example? Or maybe a math quiz dealing with absolute value (something i’m going to learn this year in 7th grade)?

**Gobli09**#125

That would be cool

Absolute value is actually quite easy. It’s just how far a number is from zero

**HappyDolphin**#129

## Some math things that could be good basis for a project!

Order of operations

Variable expressions

Writing expressions for word phrases

Related equations

Solving problems

Decimals and problem solving

Interpreting expressions

You need to add yourself to this list. Since you’re a basic, you can’t do it…but when you become member you can

Maybe one of you guys can log into the MatHS collab and publish this Rational Numbers quiz using problems that are taken straight out of my 7th grade math book (I got my math book early because I’m in K12, with credit to me)?

Question 1: 3 + (-7) is?

Answer to Question 1: 3 + (-7) = -4

Question 2: -4 + (-2) is?

Answer to Question 2: -4 + (-2) = -6

Question 3: What kind of solution will -20 + (-13) be when you solve it?

Answer to Question 3: The solution is negative because both addends are negative.

Question 4: How do you solve -25 + 35?

Answer to Question 4: You solve it using a number line.
