The solution is just written in your post.

Do you want the tutors re-tell it for you in their own words ?

Which help do you need ?

I'm not sure what you are asking here....

What you show is one way of thinking when you are asked to add 53 to 38.

The thinking is that 38 is 2 short of 40, so you take 2 of the 53 and add it to the 38, making 40, and leaving 53-2 = 51 left to add. Then 40 plus 51 is easy because there is no "carry".

In mathematical notation, the process can be displayed like this:

38 + 53 = 38 + (2 + 51) = (38 + 2) + 51 = 40 + 51 = 91

Similar to borrowing if you do not "need" to

Meant mostly as a mental technique

add 2 and subtract 2 so things balance out.

38 + 2 = 40
53 - 2 = 51
