Quantitative Gre Basic Algebra

Front 1

What does the base to the zero power equal to?

Back 1

A base to the zero power equals 1.
x^0 = 1
5^0 = 1
129^0 = 1

Front 2

What does the base

to a negative exponent equal to?

Back 2

A base to a negative exponent is the reciprocal of something.

Front 3

What happens to the exponents when you multiply the like bases?

Back 3

To multiply like bases, add the exponents.

Front 4

What happens to the exponents when you divide the like bases?

Back 4

To divide like bases, subtract the exponents.
You can divide two bases that are the same by subtracting the exponents.

Front 5

What happens to the exponents when you raise it to some power?

Back 5

Multiply the exponents of a base inside and outside of parentheses.

Front 6

Define the rules of addition or subtraction of the like bases to like powers.

Back 6

To add or subtract like bases to like powers, add or subtract the numerical coefficients of the bases.

Front 7

Define: Median

Back 7

Median is the middle number when all the terms are arranged in order. Think of the median strip, which is the middle of the road. Median = middle. Be sure to arrange the numbers in order (increasing or decreasing, it makes no difference) before you find the median. If the list has an even number of terms, put them in order and find the middle two.
Then find the average of those two terms.

Front 8

Define: Mode

Back 8

The mode is the most frequent number. Remember the mo part! Mode is the most used term. We suggest you put the numbers in order again. The one that shows up the most often is the mode.

Front 9

Define: Range

Back 9

The range is the distance from the greatest to the smallest. In other words, take the biggest
term and subtract the smallest term. Your answer is the range.
