As we up our game and figure this out, we can add variables and ugliness:)
Multiplication and Division Re-visit!
Number x Number (review)
positive x positive = positive
a. 3 x 4 = 12
b. +5(3) = 15
positive x negative
a. (+2)(-8) = -16
b. (-3) x (+3) = -9
negative x negative
a. -6(-1) = 6
b. (-3)(-5) = 15
Number x Letter (always write number first)
3 x r = 3r
q x -6 = -6q
Letter x Letter
a x b = ab
a x a = a*2
Now we can have some ADVANCED MATH FUN!!
Practice questions!
In this case, we work from the outside in...so the exponent 3 outside the brackets is "exponenting" or affecting everything INSIDE the brackets...so the 3, the x*4, AND the y*6
