  3. OBJECTIVE • Apply the order of operations • Group quantities with parentheses in a graphing calculator.

  4. New Section: VOCAB: • Terms:a single number or variable, or the product of several numbers or variables separated from another term by a + or - sign • Variables: letter representing a number • Combining Like Terms/Simplify: terms that share the same variable, then combining them together VOCAB: PEMDAS: P-parenthesis… [ or ( E-exponents… 2 M-multiplication… • or x D-division… / or : A-addition… + S-subtraction… -

  5. Examples: 1. 2 + 4 • -6 = • PEMDAS • 2 + (-24)= • MDAS -22 • 2. [1+1]2•-3 = • PEMDAS • [2]2•-3= • EMDAS • 4•-3 = • MDAS -12 2.17… -2 Math, E, E 6/35 = 2 6/35 3. -(4 + 2/5) + (6 + 4/7) =

  6. Partner Practice • Write the order in which pemdas occurs in the expression: • 2+[4-3]2•-4 • 2. How would this expression look in your calculator and Solve. • 3. Use your calculator to solve [2-6]2•-3 = 4. Simplify the expression below and write your answer as a mixed fraction. SHOW YOUR WORK! 5. Sunnie bought 4 and 2 out of 3 cups of brown sugar, 2 and 4/7 cups of fine ground sugar, and 7 out of 10 cup of natural sugar. a. How much sugar did Sunnie buy in total? b. Answer the question with a mixed fraction.

  7. Example: Combining like terms- • Simplify: 2x-3x • Combine like terms: 9xy+4xy-xy • -3z+4y-6z= • Combine like terms: (Mixed) • 6y-2z-4yz=

  8. Partner Practice 1.Write the order in which PEMDAS occurs in the expression: 2+[4-3]2•-4 2. Combine Like terms: xy+4xy-2xy+4x 3. Write the order in which pemdas occurs in the expression: 2x+[4z-3z]-4x 4. Simplify the expression below and write your answer as a mixed fraction. SHOW YOUR WORK! 6. If 42= 4•4, then what do you think 4x2=? 7. When analyzing number 5, why is it we can not combine 4xy+4xy2 8. Are the given terms different? If so, show the difference between 4x2y and 4xy2

  9. HOMEWORK DO NOT FORGET: -Title, Date, and Name on loose leaf paper -NEW Page NUMBERED

  10. NAME: DATE: Title: Group quantities with parentheses with or without a graphing calculator. • Given –(4+ 6/7) • What operation does your calculator do first when putting this in your calculator? Addition, Subtraction, Division, Multiplication (Pick One) • Write the given expression above as a mixed fraction. • Simplify: 2x-4x-9x • Combine like terms: 4x+6xy-4x • 3x+3x-2y+6y=? • How would you simplify: 6. Given the expression: 4-(2-3)3•-1 List PEMDAS and how each step applies to this problem. 7. Derrick was told he needed 1 and 2 out of 5 cups of salt for a recipe serving 6 people. He was serving 12 people, therefore, he needed double the amount of salt. • How much salt will the recipe need if Derrick is cooking for 12 people? SHOW WORK! • What if Derrick was only cooking for 3 people? What would Derrick put into the calculator to find the amount of salt he needs? PAGE #
