Answer 3

Let's solve the arithmetic expressions:

a) -0.4 + 2.5

To add these numbers, simply add their decimal parts together:

-0.4 + 2.5 = 2.1

b) 2.6 - (-0.2)

To subtract a negative number, you can think of it as adding the positive equivalent:

2.6 - (-0.2) = 2.6 + 0.2 = 2.8

So the results are:

a) -0.4 + 2.5 = 2.1

b) 2.6 - (-0.2) = 2.8
