Exam Review for JUNE 22

Math review for exam on Integers

Negative numbers represent values below zero
and positive numbers represent values above zero






an example would be above and below ground or sea level( a bird is flying 5 meters above the lake and a fish is flying 6 meters directly under the bird how much is the difference between them)
How do you figure out if a integer statement is a addition statement or subtraction?
you check the operation
eg 1+(-2)=(-1) would be a addition statement
3-(-1)=4 is a subtraction statement

Opposite integers have the same numeral but different signs they always equal 0 like
(+5) -(-5)=0 also (+3)-(-3)=0


you can also solve them on number lines


Here is a game where you can play and learn about Integers

B.E.D.M.A.S

B- Brackets ( )
E- Exponents
D- Division (in order from left to right)

M- Multiplication
A- Addition (In order from left to right)

You just have to remember to do it in order and then bring down the rest of the numbers.

Annie has been asked to calculate 1.7 + 6 ÷ 2. She claims the answer is 3.85. Do you agree? Explain why or why not.

I don't agree because Annie added 1.7 + 6 first which would make the answer 7.7. She should have divided 6 and 2 then added 1.7 to make 4.7.
