Multiplying two integers
Multiplying rational expressions
Multiplying fractions
Let $a$, $b$, $c$, and $d$ be integers with \(b \ne 0\) and \(d \ne 0\). The product of \(\frac{a}{b}\) and \(\frac{c}{d}\) is \(\frac{a}{b}•\frac{c}{d} = \frac{{a•c}}{{b•d}}\).
Multiplicative inverse property
The product of a nonzero real number and its reciprocal is 1.
Multiplicative identity property
The product of 1 and a real number equals the number itself.
Multiplication property of inequalities
Multiply each side by a positive quantity. If \(a < b\) and $c$ is positive, then \(ac < bc\). Multiply each side by a negative quantity and reverse the inequality symbol. If \(a < b\) and $c$ is negative, then \(ac > bc\).
Monomial
A polynomial in $x$ with only 1 term.
Mixture problems
Real-life problems that involve combinations of two or more quantities that make up a new or different quantity.
