Question

What is `13*4-65-:13`?

Answer 1

`47`

Explanation:

Count the number of terms first.

Calculate a single answer for each term first and then add or subtract them in the last line.
Stronger operations are done before weaker ones.

`color(red)(13xx4) - color(blue)(65 div13)`

= `color(red)(52) - color(blue)(5)`

=`47`
