Fascinating Fact:
If you swap the numbers around in addition, the answer stays the same, like flipping a pancake that lands perfectly.
In 11 Plus Maths, pupils learn that addition and subtraction are opposite operations. When adding, numbers increase, and when subtracting, they decrease. Understanding how these two work together builds the foundation for more advanced problem solving, such as working with decimals, fractions, and algebra later on.
Key Terms
- Addition: The process of finding the total when two or more numbers are combined.
