$41$ $41$

$40 + 40 \times 0 + 1 there are 3 terms$ $color(magenta)(40)color(blue)( + 40 times 0)color(red)( + 1) " there are 3 terms"$

Simplify each term to a single answer and then add or subtract in the last line.

$40 + 0 + 1$ $color(magenta)(40)color(blue)( +0)color(red)( + 1)$

= $41$ $41$

A common wrong answer is 1, obtained form simply working from left to right.

$40 + 40 = 80$ $40+40 = 80$

$80 \times 0 = 0$ $80xx0 = 0$

$0 + 1 = 1$ $0+1 = 1$

In this case addition has been done before multiplication which is a more powerful operation and should be done first.
