### Day 7 evaluating all integers

1. 1. OBJECTIVE: How do we evaluate expressions involving integers? Do Now Evaluate using the Order of Operations. 4[-5 + 5 • 4 ÷ 10 - (4 - 8 + 2)] 1
2. 2. Anticipatory Set 1.) Evaluate the following expression. -5(x + 10)2, for x = -13 2.) How do you evaluate a power if the base is negative? 3.) Evaluate the following. 22 (-2)2 23 (-2)3 2
3. 3. Anticipatory Set Continued 1.) Evaluate the following expression. -5 x + 10 , for x = -13 2.) How do you evaluate when there is absolute value symbols? 3
4. 4. 1   Evaluate the algebraic expression using the order of operations. (-3)3 ÷ x + (-2), for x = -9 4
5. 5. 2   Evaluate the algebraic expression using the order of operations. [22 + (-4) • x] - (-5), for x = -1 5
6. 6. 3   Evaluate the algebraic expression using the order of operations. -6 - 2(-5 + 2) ÷ x, for x = -3 6
7. 7. 4   Evaluate the algebraic expression using the order of operations. (-2)4 + r, for r = -10 7
8. 8. Grade: My Work: Explanation: Corrections: 1.) x + 2 - y • 7, for x = 3 and y = 5 8
9. 9. Grade: My Work: Explanation: Corrections: 2.) xy + (-7), for x = -5 and y = -4 9
10. 10. Grade: My Work: Explanation: Corrections: 4.) x3 - y, if x = -10 and y = -3 10
11. 11. Grade: My Work: Explanation: Corrections: 6.) -35 + x ÷ 6 • (-3), for x = -19 11
