milyNumber Sense and Numeracy: Order of OperationsWhen calculating expressions, we follow the order of operations:Order of Operations1. Simplify brackets.2. Then simplify powers.3. Multiply and divide.4. Then add and subtract.Example 1Example 2Simplify-3(2 - 4) – (-2 + 4).Add (-3)' to the productof -2 and 4.SolutionSolution-3(2 - 4) - (-2 + 4)= -3(-2) - (2)= 6 - 2= 4(-2)(4) + (-3)'= (-2)(4) + 9= -8 + 9= 1Practise1. Simplify. Use the order of operations.(a) 5 - (3 - 4)/(b) (5 – 7) – (3 – 4)(c) -3(-4) – (5 – 7)(d) (3)(2) – (3 + 5)(e) -(5- 9)- (-2)(2)(f) (4 - 3) - 2(3 – 4)(g) 4(-2) - (-8 + 4)3. Match each expression with thecorresponding sentence.(a) Find the sum of -3,-8, and(b) -8 is added to the product cand -2.(c) Subtract -8 from the produand -2.(d) Divide -8 by -2 and add -(c) Decrease the quotient of -by -3.i. -3(-2) + (-8)ii. -8 + (-2) + (-3)iii. -8 (-2) -(-3)iv. -8 + (-3) + (-2)v. (-3)(-2) – (-8)2. Simplify.(a) 2(-3): - 4(-2)(b) -4(-2)3 - 3(-4)²(c) (-3 - 2)2 - (2 + 4)2(d) 3(=2 +.4)3 – 2(-4 + 1):(e) 2(-1 - 3) - (1 + 3)²(f) 5(-2)2 - 3(-1- 2)3(g) 3(-1- 2) - (5- 7)3(h) 5(-2 + 1)3 -(-3-2):(i) 4(1- 3)3 - (4 - 7)2(j) -2(1- 4)3- 3(1 - 5)4. Increase the sum of -3 and 5 by5. Divide the sum of 7 and -16 by6. By how much is the sum of-8more than -4?7. How much less is the sum of -chan the product of 4 and -2?8. Divide -42 by (-2)2.9. Add -3 and 42 to the productand -2.Number Sense and Numeracy:Order of Operations
