Question

Can someone please help...

This is a quantitative (maths) question. I’m going to show the solved examples, Cena someone explain the examples to me?
Please ignore the question above and explain examples.

Answer 1

See below for explanation of the examples.

Explanation:

Left example

It is an exercise in addition, i.e. 48+122=170, the answer is written in the bottom box.

Right example

It is an exercise in subtraction, i.e. 8 1/2 - 3 1/2 = 5

The answer is written in the bottom box.

There is no indication though as to when to do the addition, and when to do the subtraction. Perhaps it would be shown in the rest of the page (not shown).
