What's the difference between 'difference' and 'sum' in maths?
‘Difference’ refers to the subtraction of one number from another. It indicates the numerical distance between two values.
‘Sum’ refers to the result of adding two or more numbers together.
How do I find the sum of two numbers?
To find the sum of two numbers, add the two numbers together. The result will be the combined total of the two numbers.
What is carrying in addition?
Regrouping, also known as carrying, is a technique used in addition when the total in one place value (like the ones or the tens) is 10 or greater.
You simply take the 1 (like the 1 in 17) and add it to the next value place over to the left. This demonstrates that a number larger than 9 can be understood to be 10 + whatever is in the ones space.
To sum up, addition is a vital foundation for all maths skills to follow. With a little bit of practice, you’ll soon understand this cornerstone of maths and will be able to tackle more complex forms of arithmetic!
