Answer:
42
Step-by-step explanation:
Given expression,
\(3\times {(12-8)\times 2+(11-9)\times 3}\)
Since, when we simplified an expression,
Then we follow the following order,
B = Bracket,
O = of
D = Division
M = multiplication
A = addition
S = subtraction,
Thus, the simplification of the given expression is as follow,
\(3\times {4\times 2+2\times 3}\)
\(=3\times (8 + 6)\)
\(=3\times 14\)
\(=42\)
