Question

The value of 0.0001289"-"0.0000000274
* 1293 + 0.0000419032 is

Answer 1

We have no bracket here so we cannot open it. We don't have to divide here too, so we just have to follow the 'MAS'. You might notice in addition, I have not added the number on the left, but the number on left to left as if a positive number is added to a negative one, they are subtracted. The number which has no sign on its left, is a negative one.
