NES Subtest 2 ACTUAL UPDATED Exam
Questions and CORRECT Answers
Intergers - CORRECT ANSWER - A whole number; a number that is not a fraction. (ex/ -
1, 0, 1, 2, 3)
Communicative Property - CORRECT ANSWER - Adding or multiplying two numbers
will always have the same answer no matter the order. : a+b = b+a AND ab = ba
Identity Property of Multiplication - CORRECT ANSWER - If you multiply a number by
one, the product is the same as that number. a x 1 = a
Identity Property of Addition - CORRECT ANSWER - If you add zero to a number, the
sum is the same as that number. a + 0 = a
Associative Property - CORRECT ANSWER - Changing the grouping of numbers will
NOT change the value. For example: (7 + 4) + 8 = 7 + (4 + 8) also works with multiplication.
Distributive Property of Multiplication - CORRECT ANSWER - The property that states
that multiplying a sum by a number is the same as multiplying each addend by the number and
then adding the products.
Multiplying Fractions - CORRECT ANSWER - Multiply the numerators and put the
product over the product of the denominators
Area of a circle - CORRECT ANSWER - A=πr²
Circumference of a circle - CORRECT ANSWER - C=2πr or C=πd
Diameter of a circle - CORRECT ANSWER - d=2r
, Pythagorean Theorem - CORRECT ANSWER - a²+b²=c²
Finding percent of a number - CORRECT ANSWER - Diving the part over the whole.
Change the percent to a fraction or decimal and multiply
Example: What is 20% of 80?
20/100 x 80 = 1600/100 = 16
or .20 x 80 = 16.00 = 16
Multiplying Inequalities - CORRECT ANSWER - When you multiply or divide by a
negative number, you must flip the inequality sign.
Point slope form - CORRECT ANSWER - y = mx + b
Slope Formula - CORRECT ANSWER - (y₂- y₁) / (x₂- x₁)
Rise/run
Rate of change - CORRECT ANSWER - A ratio that compares the amount of change in a
dependent variable to the amount of change in an independent variable.
Percent of change - CORRECT ANSWER - A ratio that compares the change in a quantity
to the original amount.
Organic compounds - CORRECT ANSWER - compounds that contain carbon-based
molecules
Covalent Bonds - CORRECT ANSWER - Bonds created by sharing electrons with other
atoms.
