It depends on the question, but if the question is, how many is there....
It usually means to <u><em>add</em></u>
(What is the question anyway?)

The distance in kilometers in scientific notation 
<h3>Scale factors</h3>
Scale factors are values or constants multiplied with a variable
If Alvin and Simon raced a distance of
kilometers and they need to race 7 times that distance in a kilometer, the distance traveled will be:
- Distance travelled =

- Distance travelled =

Hence the distance in kilometers in scientific notation

A = 5 + B
A + 5 = 2B
Let's get one of the variables on one side.
A = 5 + B
A = 2B - 5
By the transitive property
5 + B = 2B - 5
Solve for B.
5 = B - 5
10 = B
Use 10 = B in an earlier equation to find A.
A = 5 + B
A = 5 + 10
A = 15
Abe has 15$ and Ben has 10$.
Sample space ={5G, 2Y, 8R, 3P} =18 POSSIBLE OUTCOME
1st draw: P(R) = 8/18 = 4/9 = 0.444
2nd draw (no replacement, means already one Red is picked up, so the sample space has been reduced): P(another one more RED) = 7/17 =0.411
