For the numbers in the previous exercise, find out how to get each number by making the smallest number of button clicks and write the expression.

Correct Answer

(a) 8300: (8×10008 \times 1000) + (3×1003 \times 100) = 8300, Total clicks = 8 + 3 = 11 (b) 40629: (4×100004 \times 10000) + (0×10000 \times 1000) + (6×1006 \times 100) + (2×102 \times 10) + (9×19 \times 1) = 40629, Total clicks = 4 + 0 + 6 + 2 + 9 = 21 (c) 56354: (5×100005 \times 10000) + (6×10006 \times 1000) + (3×1003 \times 100) + (5×105 \times 10) + (4×14 \times 1) = 56354, Total clicks = 5 + 6 + 3 + 5 + 4 = 23 (d) 66666: (6×100006 \times 10000) + (6×10006 \times 1000) + (6×1006 \times 100) + (6×106 \times 10) + (6×16 \times 1) = 66666, Total clicks = 6 + 6 + 6 + 6 + 6 = 30 (e) 367813: (3×1000003 \times 100000) + (6×100006 \times 10000) + (7×10007 \times 1000) + (8×1008 \times 100) + (1×101 \times 10) + (3×13 \times 1) = 367813, Total clicks = 3 + 6 + 7 + 8 + 1 + 3 = 28
