Answer:

#41#

Explanation:

#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.

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

=#41#

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

#40+40 = 80#

#80xx0 = 0#

#0+1 = 1#

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