NOMOR 1
MATA
M = 1
A = 2
T = 1
Total huruf = 4
Unsur ganda = A (2)
P = 4! / 2!
P = 4 × 3 × 2 × 1 / 2 × 1
P = 4 × 3
P = 12 susunan kata
HANTU
H = 1
A = 1
N = 1
T = 1
U = 1
Total huruf = 5
Unsur ganda = –
P = 5!
P = 5 × 4 × 3 × 2 × 1
P = 20 × 3 × 2 × 1
P = 60 × 2 × 1
P = 120 × 1
P = 120 susunan kata

NOMOR 2
= 6² – 4²
= ( 6 × 6 ) – ( 4 × 4 )
= 36 – 16
= 20
Penjelasan dengan langkah-langkah:
MATA
= 4! / 2!
= 4.3.2.1 / 2.1
= 24 / 2
= 12 Susunan
HANTU
= 5!
= 5.4.3.2.1
