What does PEMDAS stand for?

Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

100

(4 + 6) × 2

10 × 2 = 20

100

3² or (3 x 3)

9

100

2 × 3 + 2

2 × 3 + 2
6 + 2 = 8

100
What is my last name?

Cho

200

6 + 3 x 2?

Multiply first, so 3 × 2 = 6 → 6 + 6 = 12

200

7 x (5 - 3) + 4

7 x (5 - 3) + 4

7 x 2 + 4

7 × 2 = 14

14 + 4 = 18

200

5³ = 5 x 5 x 5 = ____

125

200

10 × 3 − 5

10 × 3 − 5
30 − 5 = 25

Why does PEMDAS never get into arguments?

Because it always handles things in the right order.

300

True or False: Multiplication always comes before Division.

False --> they go left to right.

300

(8 − 2) ÷ 3 + 1

(8 − 2) ÷ 3 + 1

6 ÷ 3 = 2
2 + 1 = 3

300

4 + 2² × 3

4 + 2² × 3
2² = 4
4 × 3 = 12
4 + 12 = 16

300

4² + 6

4² + 6
16 + 6 = 22 ✅

300

PEMDAS doesn’t like drama —
It deals with __________ first.”

parentheses

400

18 − 6 ÷ 3 + 2²

  1. Exponent first → 22 = 42² = 422 = 4

    Now the problem becomes:

    18 − 6÷ 3+418 - 6 ÷ 3 + 418  − 6 ÷ 3 + 4

  2. Division (left to right) → 6 ÷ 3 = 26 ÷ 3 = 26 ÷ 3 =2

    Now:

    18 − 2+ 418 - 2 + 418 − 2 + 4

  3. Subtraction & Addition (left to right)
    18 − 2 = 1618 - 2 = 1618 − 2 = 16
    16 + 4 = 2016 + 4 = 2016 + 4 = 20

Final Answer: 20

400

2(4 + 3) − 5

2(4 + 3) − 5

2 × 7 = 14
14 − 5 = 9

400

(2 + 3)²

(2 + 3)²
5² = 5 x 5 = 25

400

24 ÷ 4 + 3

24 ÷ 4 + 3
6 + 3 = 9 ✅

400
What goes up but never goes down?

Your “E” in PEMDAS — Exponents.

Exponents — they go up (powers), and PEMDAS never lets them come back down the order.

500

(8 + 4) ÷ 2 × 3 − 5

  1. Parentheses first → 8+4=128 + 4 = 128+4=12

    Now:

    12÷2×3−512 ÷ 2 × 3 - 512÷2×3−5

  2. Division (left to right) → 12÷2=612 ÷ 2 = 612÷2=6

  3. Multiplication → 6×3=186 × 3 = 186×3=18

  4. Subtraction → 18−5=1318 - 5 = 1318−5=13

Final Answer: 13

500

(9 − 3)² ÷ 6

(9 − 3)² ÷ 6
6² = 36
36 ÷ 6 = 6

500

10 − 2³ × 2

10 − 2³ × 2
2³ = 8
8 × 2 = 16
10 − 16 = −6

500

(5 × 3 − 4) × 2

(5 × 3 − 4) × 2
15 − 4 = 11
11 × 2 = 22

How many of you are there?

There are two of me —

because in PEMDAS it’s M & D (Multiply and Divide) and A & S (Add and Subtract) — and they travel in pairs like troublemakers.
