Question

Write an addition expression and a subtraction expression each with a value of 2.4 x 10^-3

Answer 1

Well,

You can just add up the numbers to get 2.4.

Example:

`1.0*10^(-3)+1.4*10^(-3)=10^(-3)(1.0+1.4)=2.4*10^(-3)`

In the same way you can make a subtraction problem.

Example:

`5*10^(-3)-2.6*10^(-3)=10^(-3)(5-2.6)=2.4*10^(-3)`
