Find the value of:
(11+4)−9×1÷3 of 4

Following the BODMAS rule, operations are done in this sequence: Bracket, Of, Division, Multiplication, Addition, Subtraction.
First, solve the expression inside the bracket:

11+4=15
The expression becomes:

15−9×1÷3 of 4
Next, solve the 'of' operation:

3 of 4=3×4=12
The expression becomes:

15−9×1÷12
Next, perform the division:

1÷12=
12
1
​

The expression becomes:

15−9×
12
1
​

Perform multiplication:

9×
12
1
​
=
12
9
​
=

15×4−3
​
=
