Essential Question<\/strong> What Order Should You Use When You Evaluate an Expression?<\/p>\n

A.<\/strong>
\nJack evaluated [(7 \u00d7 2) \u2013 3] \u00f7 8 = 2 \u00d7 3.
\nTo avoid getting more than one answer, he used the order of operations given at the right.<\/p>\n

Parentheses, brackets, and braces are all used to group numbers in numerical expressions.
\n\"Envision<\/p>\n

Order of Operations<\/strong>
\n1. Evaluate inside parentheses (), brackets [ ], and braces {}.
\n2. Multiply and divide from left to right.
\n3. Add and subtract from left to right,<\/p>\n

B.<\/strong>
\nStep 1<\/strong>
\nFirst, do the operations inside the parentheses.
\n\"Envision
\nThen, evaluate the terms inside the brackets.

Essential Question<\/strong> How Can You Write a Numerical Expression to Record Calculations?<\/p>\n

A.<\/strong>
\nThe school auditorium has 546 seats on the main floor and 102 in the balcony. Every seat is filled for all of the Variety Show performances. Write an expression that shows the calculations you could use to determine how many tickets were sold.
\n\"Envision<\/p>\n

B.<\/strong>
\nThink about how you would calculate the total number of tickets.
\nAdd 546 + 102 to find the total number of seats.
\nThen multiply by the number of performances, 4.
\nSo, you need to write a numerical expression that represents:
\n“Find 4 times the sum of 546 and 102.”<\/p>\n

C.<\/strong>
\nUse numbers and symbols to write the numerical expression.
\nThe sum of 546 and 102: 546 + 102
\n4 times the sum: 4 \u00d7 (546 + 102)<\/p>\n

\n\\(\\frac{7}{8}\\) + \\(\\frac{1}{2}\\) + 1\\(\\frac{3}{4}\\)
\n\"Envision
\nBoth expressions contain the sum \\(\\frac{7}{8}\\) + \\(\\frac{1}{2}\\) + 1\\(\\frac{3}{4}\\). This is the amount of fabric needed for Jimmy’s costume.<\/p>\n

C.<\/strong>
