Subtraction is one of the first things we learn in Mathematics in school. However, a fundamental skill like subtraction is used pervasively by us in our adult life without realising it much. Being able to subtract numbers faster makes our lives easier and increases our productivity. If you are preparing for a competitive exam, being able to calculate faster will give you an edge in the competition. You can enhance your subtraction skills with a simple trick.
In this blog post, we share a simple technique to improve your subtraction skills.
Subtract in parts
Let us take a simple example first.
Suppose you want to subtract 47 – 15.
You can split the subtraction as 47, 10, 5.
First, subtract 10 from 47, then subtract 5 from the result
47 – 10 = 37
37 – 5 = 32
Easy right?
Now let us take a bit of a difficult example.
Suppose you want to subtract 487 – 236.
Let us see how we can easily split and subtract.
First, take 487 – 200 = 287
Next, 287 – 30 = 257
Then, 257 – 6 = 251
You can also split the calculation as 480 – 230 = 250 if you are comfortable.
Then, go ahead with 7 – 6 = 1. So 250 + 1 = 251.
You can split in any way you want. There is no fixed way of doing it. Split the numbers in any way that you are comfortable with.
