Question

Evaluate the following using the order of operations:

$3+6\times (5+4)÷3-7$.

Answer 1

Simplify the expression:

As we know the BODMAS rule which tells about the order in which we should solve these kind of expressions.

B stands for Bracket that means we have to solve the values which are in brackets.

O stand for OFF, Similarly D stands for Division, M stands for Multiplication, A stands for Addition and S stands for Sutraction.

These operations we should follow in sequence ie, first Bracket then Off then Division, then Addition and then Subtraction.

In given problem, we observe,

$$\begin{gathered} 3+6\times (5+4)÷3-7=3+6\times 9÷3-7 \\ =3+6\times 3-7 \\ =3+18-7 \\ =21-7 \\ =14 \end{gathered}$$

Hence, the value of expression is $14$
