TSI Math Test Questions and Verified Correct
Answers
1. PEMDAS (parenthesis, exponents, multiplication, division, addition,
subtraction) work left to right
2. Exponential Notation Ex: 6^4, 2^3, 9^10, etc.
3. Expanded Form Ex: 7x7x7, 6x6, 2x2x2x2x2, etc.
4. Standard Notation Ex: 5^2= 25; 25 is the standard notation (the answer or solution)
5. +x+ =+
6. +x- =-
7. -x- =+
8. Adding or You need a common denominator
Subtracting
fractions
9. Multiplying fractions no special rule, just multiply Ex: 2/5 x 3/9= 6/45
10. Dividing fractions flip 2nd fraction and multiply Ex: 2/5 divided by 3/9= 2/5 x 9/3
11. Solving Equations either multiply both sides of the equation by the reciprocal of the
w/ fractions fraction, or multiply both sides of the equation by the
denominator of the fraction
12. Percent Increase or De- Formula: amount of change/ original number. Ex: Find the
percent de-
crease problems crease if the price changes from $60 to $39. 60-39= 21. amount of
change= $21 original number= $60. $21/$60= 0.35. Convert
to percents. 0.35= 35%
13. Interest Formula: interest= principal x rate x time (I= PxRxT)

15. Line -A line has one dimension
-Named using any two point on a line w a two sided arrow above
them
-It can also be named using a lower-case cursive letter
16. Collinear Points Points that are on the same line
17. Plane -A plane has two dimensions
-It is represented by a shape that looks like a floor or a wall, but it
extends w/o an end
-Through any three points not on the same line there is exactly on
plane
-A plane is written using 3 non-collinear points or with upper-case
cursive letter
18. Coplanar points Points that lie in the same plane
19. Line Segment A line segment is named using both end points with a line above
them
20. Ray A ray is named using its endpoint first and then any other
point on the ray pointing to the right above them
