Short answer

Part (a) The simplified value is 19.

Part (b) The simplified value is 19.

Step-by-step solution

Part (a) Step 1. Concept Used.

According to subtraction property, the subtraction of a number is equal to the addition of its opposite. This can be expressed as follows.

$a-b=a+\left(-b\right)$

Part (a) Step 2. Calculation.

Subtract 16 from 35.

$35-16=19$

Part (b) Step 1. Concept Used.

According to subtraction property, the subtraction of a number is equal to the addition of its opposite. This can be expressed as follows.

$a-b=a+\left(-b\right)$

Part (b) Step 2. Calculation.

Add the opposite of 16 with 35.

$\begin{array}{rcl}35+\left(-16\right)& =& 35-16\\ & =& 19\end{array}$
