STEP-BY-STEP SOLUTION USING PEMDAS
Problem: 2³ × 3² ÷ 3! ÷ 4 = ?
PEMDAS RULE
PEMDAS means:
P = Parentheses
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
Important:
Multiplication and Division have the SAME
priority.
Therefore, when multiplication and division
appear together, calculate from LEFT TO RIGHT.
Also, the symbol “!” means FACTORIAL.
STEP 1: Calculate the exponents
2³ = 2 × 2 × 2
2³ = 8
And:
3² = 3 × 3
3² = 9
The expression becomes: 8 × 9 ÷ 3! ÷ 4
STEP 2: Calculate the factorial
3! means:
3 × 2 × 1
Therefore:
3! = 6
The expression becomes: 8 × 9 ÷ 6 ÷ 4
STEP 3: Calculate multiplication and division
from LEFT TO RIGHT
First: 8
× 9 = 72
Then: 72
÷ 6 = 12
Then: 12
÷ 4 = 3
FINAL ANSWER:
3
IMPORTANT
NOTES
1. The symbol “!” means
factorial.
3! = 3 × 2 × 1 = 6
2. Do not confuse: 3² = 9
with: 3!
= 6
They are completely different operations.
3. Multiplication and
division have the SAME priority.
So: 8 ×
9 ÷ 6 ÷ 4
must be calculated from LEFT TO RIGHT:
8 × 9 = 72
72 ÷ 6 = 12
12 ÷ 4 = 3
4. Do NOT calculate: 9 ÷ 6 ÷ 4
as: 9 ÷
(6 ÷ 4)
because there are no parentheses.
SOLUTION SUMMARY
2³ × 3² ÷ 3! ÷ 4 = ?
= 8 × 9 ÷ 3! ÷ 4
= 8 × 9 ÷ 6 ÷ 4
= 72 ÷ 6 ÷ 4
= 12 ÷ 4
= 3

PENYELESAIAN
LANGKAH DEMI LANGKAH MENGGUNAKAN PEMDAS
Soal: 2³
× 3² ÷ 3! ÷ 4 = ?
ATURAN
PEMDAS
PEMDAS berarti:
P = Parentheses = Tanda Kurung
E = Exponents = Pangkat
M = Multiplication = Perkalian
D = Division = Pembagian
A = Addition = Penjumlahan
S = Subtraction = Pengurangan
Penting:
Perkalian dan pembagian mempunyai PRIORITAS
YANG SAMA.
Jika perkalian dan pembagian muncul
bersama-sama, kerjakan dari KIRI KE KANAN.
Selain itu, tanda “!” berarti FAKTORIAL.
LANGKAH 1: Kerjakan pangkat
2³ = 2 × 2 × 2
2³ = 8
Kemudian:
3² = 3 × 3
3² = 9
Soal menjadi:
8 × 9 ÷ 3! ÷ 4
LANGKAH 2: Kerjakan faktorial
3! berarti:
3 × 2 × 1
Jadi: 3!
= 6
Soal menjadi:
8 × 9 ÷ 6 ÷ 4
LANGKAH 3: Kerjakan perkalian dan pembagian
dari KIRI KE KANAN
Pertama:
8 × 9 = 72
Kemudian:
72 ÷ 6 = 12
Kemudian:
12 ÷ 4 = 3
JAWABAN AKHIR:
3
CATATAN
PALING PENTING
1. Tanda “!” berarti faktorial.
3! = 3 × 2 × 1 = 6
2. Jangan tertukar antara: 3² = 9
dengan:
3! = 6
Keduanya adalah operasi yang berbeda.
3. Perkalian dan pembagian
mempunyai PRIORITAS YANG SAMA.
Jadi: 8
× 9 ÷ 6 ÷ 4
harus dikerjakan dari KIRI KE KANAN:
8 × 9 = 72
72 ÷ 6 = 12
12 ÷ 4 = 3
4. JANGAN mengerjakan: 9 ÷ 6 ÷ 4
menjadi:
9 ÷ (6 ÷ 4)
karena tidak ada tanda kurung.
RINGKASAN PENYELESAIAN
(TANPA KETERANGAN)
2³ × 3² ÷ 3! ÷ 4 = ?
= 8 × 9 ÷ 3! ÷ 4
= 8 × 9 ÷ 6 ÷ 4
= 72 ÷ 6 ÷ 4
= 12 ÷ 4
= 3
JAWABAN = 3
