The PEMDAS rule states that operations in parentheses must be performed first, followed by exponents, then multiplication and division from left to right, and finally addition and subtraction from left to right. Parentheses group elements together and specify the order of operations. Multiplication combines equal groups, division splits a quantity into equal parts, addition combines quantities, and subtraction removes from a total quantity. Several example calculations are provided to demonstrate applying the PEMDAS rule.

1. S
RULE
PEMDAS rule states that the order
of operation starts with the parentheses
first or the calculation which is enclosed in
brackets. Then the operation is performed
on exponents(degree or square roots) and
later we do operations on multiplication &
division and at last addition and subtraction

Parentheses or “round brackets”
are the familiar ( ) symbols used in pairs to
group things together or specify the order of
operations in an equation.

3. MULTIP
LICATIO
N
In math, to multiply means to add
equal groups. When we multiply, the number of
things in the group increases. The two factors
and the product are parts of a multiplication
problem.

4. DIVI
SIO
N
In math, a division is a process of
splitting a specific amount into equal
parts.

5. ADDI
TION
Addition is a way of combining
things and counting them together as
one large group. Addition in math is a
process of combining two or more
numbers.

6. SUBT
RATIO
N In math, to subtract means to take
away from a group or a number of things.
When we subtract, the number of things in the
group reduces or becomes less.
The minuend, subtrahend, and difference are
parts of a subtraction problem.

S
Perform the following
operations observing the
PMDAS rule.
 7 + (6 – 3 + 2) x 4 = N
 (40 ÷ 5) + 4 = N
 56 ÷ (7 x 2) – 2 + 35 = N
 5 x 2 - 3 + (6 ÷ 2)= N
 9 x 4 – (20 ÷ 5 + 3)= N
 36 ÷ (6 – 3)= N
 15 ÷ (2 x 2 + 1) – 6 ÷ 3 = N
 7 + (6 – 3 + 2) x 4 = N
