Answer 2

We need to recall the following PEMDAS rule.

The order of mathematical operations is: Parenthesis, Exponents, Multiplication and Division, Addition, and Subtraction (from left to right direction)

Given:

$A$ means $+$ , $B$ means $-$ , $C$ means $\times$ , $D$ means $/$

To find: $100D20C3A10B5$

From the given information, we get

$100D20C3A10B5=\frac{100}{20}\times3+10-5$

Using the PEMDAS rule, we get

$\frac{100}{20}\times3+10-5=5\times3+10-5$

$\frac{100}{20}\times3+10-5=15+10-5$

$\frac{100}{20}\times3+10-5=25-5$

$\frac{100}{20}\times3+10-5=20$

Hence, $100D20C3A10B5=20$
