Multiplication and division are inverse operations, just as addition and subtraction are. You will come across exponents frequently in algebra, so it is helpful to know how to work with these types of expressions. A YouTube element has been excluded from this version of the text. All rights reserved. When the operations are not the same, as in 2 + 3 10, some may be given preference over others. Note how we kept the sign in front of each term. Multiply each term by 5x. Exponents are powers or indices. Theres no brackets or exponents to calculate, so the next thing on the list is Now add the third number. If the signs dont match (one positive and one negative number) we will subtract the numbers (as if they were all positive) and then use the sign from the larger number. It is important to be careful with negative signs when you are using the distributive property. ESI-0099093 (Think Math).

Are you ready to master the laws of exponents and learn how to Multiply Exponents with the Same Base with ease? Add numbers in the first set of parentheses. Using a number as an exponent (e.g., 58 = 390625) has, in general, the most powerful effect; using the same number as a multiplier (e.g., 5 8 = 40) has a weaker effect; addition has, in general, the weakest effect (e.g., 5 + 8 = 13). When both numbers are negative, the quotient is positive. \(\frac{4}{1}\left( -\frac{2}{3} \right)\left( -\frac{1}{6} \right)\). The "exponent", being 3 in this example, stands for however many times the value is being multiplied. The first set of parentheses is a grouping symbol. This tells us that we are raising a power to a power and must multiply the exponents. Remember that a fraction bar also indicates division, so a negative sign in front of a fraction goes with the numerator, the denominator, or the whole fraction: \(-\frac{3}{4}=\frac{-3}{4}=\frac{3}{-4}\). \(\frac{24}{1}\left( -\frac{6}{5} \right)=-\frac{144}{5}\), \(24\div \left( -\frac{5}{6} \right)=-\frac{144}{5}\), Find \(4\,\left( -\frac{2}{3} \right)\,\div \left( -6 \right)\). \(\begin{array}{c}\frac{5-\left[3+\left(-12\right)\right]}{3^{2}+2}\\\\\frac{5-\left[-9\right]}{3^{2}+2}\end{array}\), \(\begin{array}{c}\frac{5-\left[-9\right]}{3^{2}+2}\\\\\frac{14}{3^{2}+2}\end{array}\). Grouping symbols are handled first. For all real numbers a, b, and c, \(a(b+c)=ab+ac\). With whole numbers, you can think of multiplication as repeated addition. Use the box below to write down a few thoughts about how you would simplify this expression with decimals and grouping symbols.
