Answer:

452+(783-546)

Step-by-step explanation:

Add 452 ; 452+

the difference of 783 and 546 ; 783-546

You add in the parentheses so that you're adding 452 to the difference of the two other numbers instead of to 783.

Illusion [34]

$\frac{-1}{3} + \frac{-3}{5}$
You need to use the equation for adding fractions, which is $\frac{a}{b} + \frac{c}{d} =(ad+bc)/bd$

In this case, a=-1, b=3, c=-3, d=5.

$
