2: PEMDAS | Parentheses Exponents Multiply and Divide (cousins) Add and Subtraction (cousins) | Example: 8+5(6-3)*6= 8+5(3)*6 8+5*18 8+90 | These are a few problems for you to try.. 1. 3+(8*6)-5*12 2. 5*6(9*10)+15-6 | Example: 12+2(5*9)-15= 12+2(45)-15 12+32-675 44-627

3: Fractions | 1.Numerator - the number above the bar. 2.Denominator - the number below the line. ~ Don't forget if the denominators are the same keep them. ~Don't forget to simplify. | Problems to try: 1. 6/7+ 3/7= 2. 6/12 -2/24= 3. 9/18 + 1/2 = | Example: 6/18 + 4/18= | Example: 18/16 - 9/16 =

4: Area of Geometric Shapes | Area of a Trapezoid formula: A 1/2h (b1 +b2 ) Area of a Triangle formula: A 1/2 bh Circumference of a Circle formula: 3.14d Area of a Circle: 3.14 (r2) Area of a Rectangle: b(h) | A 1/2h (b1 + b2) A 1/2 9 (6+7) A 1/2 9 (13) A 1/2 117 A 0.5 117 A 58.5 | 9 | 6 | 7

5: Equations | -Equations is when you use a variable to replace the unknown number. - Equations is when you do the opposite of the equation sign. | Example: 2x-4=10 +4 +4 2x=14 x=7 | Here is a problem for you to try.. 1) 10 + 5x = 40 2) 5x + 1 = - 39 3) 3x + 9 = 42 | Example: 8+x=3 -3 -3 x=5
