Question

What is 67+90-1? people laugh at me because i 'don't know this'

Answer 1

Using DMAS rule (Division first then Multiplication, then Addition and lastly Subtraction)

Hence we will add 67 and 90 first

`= 67 + 90 - 1`

Then subtract 157 and 1

`= 157 - 1`

`= 156`

Hence the answer is 156
