1) Compute mixed operations problems involving addition, subtraction, multiplication, division, and brackets of up to two operations with numbers up to seven digits. 2) Solve word problems involving mixed operations to find totals, using vertical form layout and performing operations in order of operations. 3) Examples include computing 1426 × 32 + 61898, 427480 – 15400 ÷ 25, (1450 + 20412) × 15, and (34 + 46) × (84 - 23).

1. Learning Outcomes
Compute mixed operations problem involving
addition and multiplication
Compute mixed operations problem involving
subtraction and division.
Compute mixed operations problem involving
brackets.
Solve problems involving mixed operation number
of up to seven digits.

2. Compute mixed operations problems involving addition and
multiplication
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. Compute mixed operations problem involving subtraction and
division.
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. 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. Example 2:
( 34 + 46 ) × (84 -23) =
Perform in
bracket first
Then
solve it Step 1 :
34
+ -
84
Then 46 23
multiply the 80 61
answer
Multiply
using vertical
form or
Step 2 :
80 × 61
Write the
answer
4880

6. Solve problems involving mixed operations on numbers of up
to 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
