Pre-Algebra 28 - Raising Products and Quotients to Powers
Any expression consisting of multiplied and divided terms can be enclosed in parentheses and raised to a power. This can then be simplified using the rules for multiplying exponents.
Why U
Pre-Algebra 26 - Simplifying Mixed Exponential Expressions
Exponential expressions with multiplied and divided terms can be simplified using the rules of adding and subtracting exponents.
Why U
Pre-Algebra 14 - Creating Common Denominators
Addition and subtraction of fractions with different denominators requires creating a "common" denominator. Using the number line, this mysterious process can be easily visualized.
Why U
Pre-Algebra 29 - Roots and Unit Fraction Exponents
Exponents can not only be integers. They can also be fractions. Using the rules of exponents, we can see why a number raised to the power "one over n" is equivalent to the nth root of that number.
Why U
Pre-Algebra 23 - Scientific Notation
Scientific notation allows us to more easily express very large or very small numbers encountered in engineering and science. Using exponents, we can convert standard decimal numbers into scientific notation and vice versa.
Why U
Pre-Algebra 12 - Arithmetic Operations With Fractions
Arithmetic operations with fractions can be visualized using the number line. This chapter starts by adding fractions with the same denominators and explains the logic behind multiplication of fractions.
Why U
Pre-Algebra 32 - Irrational Numbers
Although the Greeks initially thought all numeric qualities could be represented by the ratio of two integers, i.e. rational numbers, we now know that not all numbers are rational. How do we know this?
Why U
Pre-Algebra 10 - Factoring
Any natural number can be decomposed into a product of prime factors. Prime factorization is fundamental to many arithmetic operations involving fractions.
Why U
Pre-Algebra 27 - Raising Exponential Expressions to Powers
If a term raised to a power is enclosed in parentheses and then raised to another power, this expression can be simplified using the rules of multiplying exponents.
Why U
Pre-Algebra 21 - Exponentiation
Exponentiation is shorthand for repeated multiplication, just like multiplication is shorthand for repeated addition. Multiplied or divided exponential terms with like bases can be combined by adding or subtracting their exponents.
