Standard form means that a number is less than 10 and in the form 10^x.
Example: 4 x 10^1, 9.67 x 10^2 or 3 x 10^-5
3a + 3b-2c-2d
a= number of hearts
b= number of diamons
c= number of clubs
d= number of spades
if you draw 3hearts, 2 diamonds, and 1 spade, just replace a=3, b=2, c=0, d=1
3(3) + 3(2)-2(0)-2(1)
Multiply each term and add the results:
