Addition of numbers
Numbers should be arranged correctly according to their place value. When adding we start from ones. If there is any carrying, then we carry 1 ten to tens.
We continue in that order until all numbers are added correctly.
Activity
Therefore, the same will be done towards word sums.
Activity:
Subtraction of members with regrouping and without regrouping
Numbers should be arranged correctly according to their place value. When subtracting we begin with or start handling with one. If there is borrowing (re-grouping). It is done in groups of tens.
That order is done until all numbers are completed.
Example
Activity:
Mk mathematics book three pages 48, 50 and 52
Primary school mathematics book 3 pages 16 and 33
Word sums involving subtractions
The same will be done in handling word sums
Activity:
Multiplying two digits by two.
Example; 1
12 x 13
12
x 13
36
+ 120
156
Example 2
12 x 13 Expand 12 10 + 2
10 x 13 = 130
2 x 13 = + 26
156
