If "A" denotes "multiplied by", "B" denotes "subtracted from", "C" denotes "added to" and "D" denotes "divided by", then evaluate the expression:
8 B 31 C 49 D 7 A 16=?

Let's replace the symbols with their corresponding mathematical operators:
A→×

B→−

C→+

D→÷

Substituting these into the given expression:

8−31+49÷7×16
Applying the BODMAS rule (Division, Multiplication, Addition, Subtraction):

Division: 49÷7=7

Expression becomes: 8−31+7×16
Multiplication: 7×16=112

Expression becomes: 8−31+112
Addition: Combine positive terms (8+112=120)

Expression becomes: 120−31
Subtraction: 120−31=89

The final value is 89.
