TSI Math test (2023 Updated ) Questions and Answers (100% Verified) PEMDAS - Answer (parenthesis, exponents, multiplication, division, addition, subtraction) work left to right Exponential Notation - Answer Ex: 6^4, 2^3, 9^10, etc. Expanded Form - Answer Ex: 7x7x7, 6x6, 2x2x2x2x2, etc. Standard Notation - Answer Ex: 5^2= 25; 25 i s the standard notation (the answer or solution) +x+ - Answer =+ +x- - Answer = - -x- - Answer =+ Adding or Subtracting fractions - Answer You need a common denominator Multiplying fractions - Answer no special rule, just multiply Ex: 2/5 x 3 /9= 6/45 Dividing fractions - Answer flip 2nd fraction and multiply Ex: 2/5 divided by 3/9= 2/5 x 9/3 Solving Equations w/ fractions - Answer either multiply both sides of the equation by the reciprocal of the fraction, or multiply both sides of the equation by the denominator of the fraction Percent Increase or Decrease problems - Answer Formula: amount of change/ original number. Ex: Find the percent decrease 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% Interest - Answer Formula: interest= principal x rate x time (I= PxRxT) Point - Answer -A point has no dimension -It is represented by a dot -A point is written using an upper -case letter Line - Answer -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 Collinear Points - Answer Points that are on the same line Plane - Answer -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 one plane -A plane is written using 3 non -collinear points or with upper -case curs ive letter Coplanar points - Answer Points that lie in the same plane Line Segment - Answer A line segment is named using both end points with a line above them Ray - Answer A ray is named using its endpoint first and then any other point on the ray pointing to the right above them Intersecting lines - Answer 2 lines that share exactly one point Parallel lines - Answer 2 lines that are always the same distance apart and never touch Perpendicular lines - Answer The relationship between 2 li nes which meet at a right angle (90degrees). Perpendicular lines= 2 lines intersect at a right angle Right angle - Answer 90 degrees Straight angle - Answer 180 degrees Acute angle - Answer between 0 degrees and 90 degrees Obtuse angle - Answer between 90 degrees and 180 degrees Complementary angles - Answer 2 angles that have the sum of 90 degrees Supplementary angles - Answer 2 angles that have the sum of 180 degrees the sum of the angle measures in a triangle - Answer 180 degrees Acute triangle - Answer All angles are acute Right triangle - Answer One angle is right Obtuse triangle - Answer One angle is obtuse Scalene triangle - Answer All sides have different lengths
