Pick ALL the answers that are correct. What should you remember about absolute value?

• It's a magic positive machine

• The absolute value symbols are just like parentheses for the order of operation

• Absolute value means do the opposite always

• You never have to calculate inside the absolute value symbols

• These are always too hard to understand

A good way to determine if a number is prime.

• Just guess

• If it's odd it's probably prime

• take all the odd numbers and if they do not divide evenly by 3 or 5 they are likely prime

• Even numbers are sometimes prime

• Put paint primer on your ACT test as a joke

A strategy you can use when the ACT says something about just "a number" is:

• The little number strategy: use 2 and maybe 3 if needed

• Use the number 1

• Use zero

• just use a number like 10

• use your age and make it negative

CCSS.7.EE.B.3

What does it mean when you see 4.5<x<27.8?

• You probably need to solve for x.

• Multiply everything by 10 so you don't have decimals.

• It's a ratio.

• X is in-between the 2 numbers shown.

• It should be your last question on the ACT.
