MATHEMATICS

SENTENCE EQUATION

It’s very simple. You have a sentence like “Bob

swam 6 meters more than Joe”. Then you get the

names “Bob and Joe” and the 6 meters and make

something like this.

B=J+6m

Simple right

ORDER OF OPERATION

Order of operation is problem that looks like this

“(9X3)+5-2x4=“. The secret is B.E.D.M.A.S.

Brackets, Exponentiation, Division, Multiplication,

Addition, Subtraction.

You must do them in this order or they will go

wrong.

By the way the answer is 24.

PERFECT SQUARE

The perfect square of a number is a number times

its self. I’ll give you the first 15.

1=1 2=4 3=9 4=16 5=25 6=36 7=49 8=64 9=81

10=100 11=121 12=144 13=169 14=196 15=225.

FACTORS

A Factor is the number that are multiplying each

other.

EX. 6x5=30 3x3=9 4x8=32

The numbers in red are the factors.

GREATEST COMMON FACTOR

The greatest common factor or GCF is the largest

number that two numbers have in comparison.

EX. The GCF of 9 and 6 is 3 because nine can go

into three and three is the largest number that nine

and six have in common.

REAL NUMBERS

Real Number is pretty much all the numbers like

Integers, rational numbers, whole numbers and

natural numbers.

ADD AND SUBTRACT INTEGERS

Integers are numbers below 0 so they look like this

-1 -2 -3.

To add them is like subtracting them so -1+-4=-1--

4= -5

To subtract its like adding them so -1-4=-1+4= 3

DIVIDING AND MULTIPLYING INTEGERS

It’s the same as in adding and subtracting integers.

To make a good under standing of this you can see

this tip below.

positive x positive= positive negative x negative =

positive

Positive x negative = negative negative x positive

= negative

NUMBER ROOTS

The square root of a number is the number divided

by 2.

EX. The square rout of 4 is 2

The cubed rout of a number is the number times it

self times it self.

EX. 3x3x3=27
