Mixed Operations

  1. 1. Learning OutcomesCompute mixed operations problem involvingaddition and multiplicationCompute mixed operations problem involvingsubtraction and division.Compute mixed operations problem involvingbrackets.Solve problems involving mixed operation numberof up to seven digits.
  2. 2. Compute mixed operations problems involving addition andmultiplication Example 1: Do Multiplication first 1426 × 32 + 61898 = Then solve it 14246 x 32 28492 + 427380 455872 Arrange in vertical form Then 455872 solve it + 61898 517770 517770
  3. 3. Compute mixed operations problem involving subtraction anddivision. Example 1: 427480 – 15400 ÷ 25 = Point to note : Mixed operations are limited not more than two operations Step 1: Do the division operation first 427480 – 15400 ÷ 25 = Step 2: Do the division operation in vertical form 15400 ÷ 25 = 616 Step 3: 427480 - 616 426864
  4. 4. Compute mixed operations problems involving brackets Example 1:. ( 1450 + 20412 ) × 15 = Do operation in the bracket Then first solve it Step 1 : 1450 + 20412 Then 21862 multiply the answer by 15 Step 2 : 21862 × 15 Write the answer 53280
  5. 5. Example 2: ( 34 + 46 ) × (84 -23) = Perform in bracket first Then solve it Step 1 : 34 + - 84 Then 46 23multiply the 80 61 answer Multiply using vertical form or Step 2 : 80 × 61 Write the answer 4880
  6. 6. Solve problems involving mixed operations on numbers of upto seven digits. Example 1: There are 412 boys and 318 girls are sitting in and exam. If each of them gets four books, how many books do they get altogether? Step 1; Understanding the problem, to find the books altogether. Step 2 ; Devise a plan using vertical form add 412 and 318. Step 3 ; 412 + 318 730 Every body gets four books. Step 4 ; Carry out the plan. Checking the solution. 730 × 4 = 2920
