Explanation:
23 – [23 – {23 – (23 – 23 – 23)}]
= 23 – [23 – {23 – (0 – 23)}]
= 23 – [23 – {23 – (– 23)}]
= 23 – [23 – {23 + 23}]
= 23 – [23 – 23 – 23]
= 23 – [0 – 23]
= 23 – [– 23]
= 23 + 23
= 46

25683
25973
Explanation:
Let the missing number be x.
98643 – 21748 = 51212 + x
x = 98643 – 21748 – 51212
x = 25683
10725.8.4 × 6.5 + 4.6 × 11.5 = ? ÷ 4
410
420
430
440
Explanation:
Let the missing number be x.
8.4 × 6.5 + 4.6 × 11.5 = x ÷ 4
54.6 + 52.9 = 4x
107.5 = 4x
x = 107.5/5
x = 430
