Quantities

This video lesson shows an animation and exercises of how to compare numbers in a fun and effective manner. This is geared towards elementary aged students.

This lesson will look at an example involving factoring. The given information will assist in learning how to simplify a rational expression by factoring out the numerator. This lesson will give a step by step explanation to better explain the concept.

If you subtract the lowest number from the biggest, you get the range. The mean, or average, of a set of numbers is found by dividing the sum of the numbers by the amount of numbers added. The middle number when numbers are arranged in order. If there are two middle numbers, the median is the average of the two. The number or numbers that occur most often in a set of numbers is the mode.

The inverse of a matrix is the same idea as the reciprocal of a number.

This lesson will look at an example involving graphing. The given information will assist in learning how to determine the solution of a system of inequalities by graphing. This lesson will give a step by step explanation to better explain the concept.

A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, where i2 = −1

The inverse of a atrix is the same idea as the reciprocal of a number.

Matrix inversion is the process of finding the matrix B that satisfies the prior equation for a given invertible matrix A. The determinant of a matrix can be defined, for example using the Leibniz formula, for matrices with entries in any commutative ring. Briefly, a ring is a structure where addition, subtraction, and multiplication are defined.

This lesson will look at an example involving polynomials. The given information will assist in learning how to determine the equation of a polynomial given two zeros. This lesson will give a step by step explanation to better explain the concept.
