2 x 5 x 22 x 1 + 5 x 22 ÷ 2 + 3 + 5 + 3
= 10 x 22 + 5 x 11 + 11
= 220 + 55 +11
= 275 + 11
= 286
2 x 18 x 22 x 1 + 2 x 24 x 22 x 1 + 4 x (24-18) ÷ 2
= 36 x 22 + 48 x 22 + 4 x 6 ÷ 2
= 792 + 1056 + 24 ÷ 2
= 792 + 1056 + 12
= 1860
= 10 x 22 + 5 x 11 + 11
= 220 + 55 +11
= 275 + 11
= 286
2 x 18 x 22 x 1 + 2 x 24 x 22 x 1 + 4 x (24-18) ÷ 2
= 36 x 22 + 48 x 22 + 4 x 6 ÷ 2
= 792 + 1056 + 24 ÷ 2
= 792 + 1056 + 12
= 1860
