• Grouping Symbols ( ) [ ]• Exponents• Multiply or Divide *** Left to Right• Add of Subtract *** Left to Right

Order of Operation

Distributive Property

• 3(5x+7) -3 15x+21-3 15x+18

Mult. Div. Integers

• -2*-3 6

Equation• A math sentence that

contains numbers, variables an equal sign.

**WE SOLVE THEM**

Mult. Div. Equation• Same + Dif. -

Two-Step Equation

• Ex. 2x+4=6 -4 -4 2x=2 2 2 x=1

Inequality

• A mathematical sentence that contains… < > ,< > 15

x > 15

Finding Solution

• Ex. Find four solution of y=2x-1 *Your in charge you make it* X Y -1 -3 0 -1 1 1 2 3

Linear Equation

• All linear equation have two variables which appear in separate terms and do not have a exponent larger than one. When we graph a linear equation it forms a LINE.

ExamplesY=2x-1Y=3x

Y=x+5

Non ExamplesY= x2+1Y=2x3Y= 3 x

Y-x+2

X Y-3 10 41 52 63 7

Numbers

Prime Numbers• A number that has only 2

factors ONE & ITSELF Ex. 17, 3, 19, 23, 7 ***Neither Zero or One are

Prime or Composite***

Composite Numbers• A number that has only 2

factors. Ex. 4,8,6,148,112

Factor• A number that will divide

evenly into another number.Ex. List the factors of 121, 2, 3, 4, 12

Divisibilitary

# divis. by IF 2 If it last number is even. 3 If the sum of the digit is divis. By 3 4 If the last 2 digits is div. 4 5 If the # is div. by 5 or 0 8 The last three digits. (add) 9 If the sun of the digits is div. by 9 10 If the last number ends with 0

Scale

• The scale gives the relationship between the measurements on a drawing or model and the measurement of a real object.

10in. Ex. 1 inch = 3 feet 5in.**There the same** 30ft

15ft

Similar Figures

Are shapes with the same shape but different size.

• Angles have the same measures, sides are proportional.
