The purpose of the Class 1 Math Olympiad Questions is to help students understand different areas of mathematics and improve their skills. It contains detailed notes about IMO Class 1 Chapter 3: Subtraction – (two digits). Using worksheets and previous year’s question papers can help students improve their computation skills and boost self-assurance when tackling challenging mathematical problems.
IMO Class 1 Chapter 3: Subtraction – (two digits) detailed notes
Primary Subtraction
Subtraction or deduction is the process of taking something out of a group of things. When subtracting, we use the minus (-) sign.
Example 1: If we take away two stars from the group of five stars, we will still have three stars.
Example 2: Subtract 3 from 7
7 – 3 = 4
Example 3: Subtract 4 from 9
9 – 4 = 5
Subtracting Zero
Any number would have the same answer if you subtracted 0 from it.
Example:7 – 0 = 7
Subtracting a Number from Itself
The result of subtracting a number from itself is always zero.
Example:8 – 8 = 0
Descriptive subtraction
Example 1: Nine birds are perched on a tree. How many birds are still on the tree if five fly off?
Number of birds on a tree = 9
Number of birds fly away = 5
So, the number of birds left on the tree is 9 – 5 = 4
Example 2: A van is carrying twelve people. How many people are still in the van if two people got out?
Number of people on a van = 12
Number of people get down = 2
So, the number of people remaining on the van 12 – 2 = 10
Benefits of Math Olympiad
