100 + 300 – 400 + 500 – 1.000 + 2 =
= 400 – 400 + 500 – 1.000 + 2
= 0 + 500 – 1.000 + 2
= 500 – 1.000 + 2
= -500 + 2
= (-500 – 2)
= –498
_____________
4! + 3! – 2! × 1! =
= (4 × 3 × 2 × 1) + (3 × 2 × 1) – (2 × 1) × (1 × 1)
= (12 × 2 × 1) + (6 × 1) – 2 × 1
= (24 × 1) + 6 – (2 × 1)
= 24 + 6 – 2
= 30 – 2
= 28
Penjelasan dengan langkah-langkah:
100 + 300 – 400 + 500 – 1.000 + 2
= 400 – 400 + 500 – 1.000 + 2
= 0 + 500 – 1.000 + 2
= 500 – 1.000 + 2
= -500 + 2
= –498
–
4! + 3! – 2! × 1!
= (4.3.2.1) + (3.2.1) – (2.1) × (1.1)
= 24 + 6 – 2 × 1
= 24 + 6 – 2
= 30 – 2
= 28
