These are all the numbers that can be expressed in a fraction form where m and n are integers and the bottom denominator is not 0. These numbers, when expressed as decimals, end or repeat (includes repeating decimals and fractions)
These are all the non-terminating numbers and non-repeating decimals (includes pi)
These are all real and imaginary numbers. It is written of the form a + bi, where "a" is a real number and "bi" is an imaginary part.
a + 0 = a, 0 + a = a (additive identiy) ORRRR a x 1 = a, 1 x a = 1 (multiplicative identity)
How do you determine the determinant?
In 2 x 2 matrices: ad - bc ... . . . . ... In 3 x 3 matrices: Find the minor
What is the rule for multiplying matrices?
The number of columns in the first matrix MUST EQUAL the number of rows in the second matrix.
