Vocabulary... In Quantitative?
When students think about studying vocabulary, they usually think of the Critical Reading section, especially those Sentence Completions! However, the Quantitative section also has special vocabulary that's good to know:
A is for: Absolute Value
Absolute Value = measures the distance between a number and 0 on the number line. That means that -2 and 2 have the same absolute value, as do all matching positive and negative numbers, because they are the same number of points away from 0.
B is for: Binomials
Does this look familiar? (x+1)(x+2)
This type of equation requires you to multiply 2 binomials (the equations inside the parentheses). Use the FOIL acronym to solve them!
F (multiply First numerals)
O (multiply Outer numerals)
I (multiply Inner numerals)
L (multiply Last numerals)
Try this problem for practice!
C is for: Consecutive Integers
When this phrase is used to describe a list of numbers, it simply means that they are listed in order of least to greatest, and that no integers are skipped. Ex.: -2, -1, 0, 1 is a list of consecutive integers.
D is for: Distinct Numbers
This term is much simpler than it seems! It describes a set of numbers in which all the numbers are different. 5, 6, 7, 8 are distinct numbers. 5, 5, 7, 8 are not.
E is for: Exponents
Exponents raise numbers to a power, and express how many times the number has been multiplied by itself. 2^3 means 2 x 2 x 2 = 8. When you multiply numbers with the same base and exponents, you add the exponents together: 2^3 x 2^4 = 2^7.
F is for: Functions
In geometry, functions show information about a graph a**ebraically. For example, a line equation in the form of y = mx + b can also be expressed as the function f(x) = mx +b.
