FAQs
Number next to a Letter (variable) means Multiply
4xIf x = -3
Then substitute amp multiply
4(-3) = -12
12a + -2bIf a = 5 b = -3
Then substitute amp multiply
12(5) + -2(-3) = 66
So do numbers next to ( ) and letters next to letters xy = xy
4(x) = 4x(-2)(a) = -2a
ab = ab4f g = 4fg
Addition and Subtraction are snobs They just combine with their own kind They form cliques
3x ndash 3a + 7 + 6x + 2a = 9x ndash a + 7

Understanding Algebraic Culture is the Key to Success
23 = 2 divide 3
Numbers come with Signs (+ -)The sign is in front
Remember These are the same thing5 ndash 3 = 2
5 + - 3 = 2Because Subtraction is Adding the Opposite
If you are confused Circle the number amp the sign in front then do the math
2 ndash 56 + 7 ndash 8 ndash 10 = - 65
ABSOLUTE VALUE
The absolute value is always positive
The absolute value of 5 is 5The absolute value of -5 is 5
To solve drop the bars and make the inside number positive
Watch Out -6 = - 6 because the negative is lurking outside the bars
ALGEBRA OPPOSITES
Opposite of Multiplication is Division

Positive Negative Numbers
The opposite of -5 is 5

Number next to a Letter (variable) means Multiply
4xIf x = -3
Then substitute amp multiply
4(-3) = -12
12a + -2bIf a = 5 b = -3
Then substitute amp multiply

So do numbers next to ( ) and letters next to letters xy = xy

1 Steal the ldquoardquo and give it to the last term (Multiply)1
5 Is there a number in front of the xsup2 amp does it have 3 terms Yes Jail Break
NO
Then it is Prime
(canrsquot factor)
Example 2xsup2 + 7x + 3
xsup2 + 7x + 6 (23)
( x + 6 ) ( x + 1 )3 Arrested and Caught - Divide last terms by ldquoardquo
( x + 62 ) ( x + 12 )
4 Beat it Down - (reduce fractions)
( x + 3 ) ( x + 12 )
5 Parole (kick denominator to the front)(x + 3 ) ( 2 x + 1 )
