Answer:

36

Step-by-step explanation:

we have the equation:

[tex]40-\frac{1}{10}*40\\[/tex]

the fist thing we have to solve is the multiplication of 1/10 *40 since it has priority over the sum:

[tex]40 -\frac{40}{10}[/tex]

Now we solve fot the quotient of  40/10

[tex]= 40 - 4[/tex]

and finally, we have

[tex]40 -\frac{1}{10}*40 = 36[/tex]
