268 = 26 − (6 + 2) = 2662 = 202 = 18
26 + 8 = 26 + (4 + 4) = 26 + 4 + 4 = 30 + 4 = 34
326 = 32 − (2 + 4) = 3224 = 304 = 26
27 + 8 = 27 + (3 + 5) = 27 + 3 + 5 = 30 + 5 = 35
759 = 75 − (5 + 4) = 7554 = 704 = 66
86 + 7 = 86 + (4 + 3) = 86 + 4 + 3 = 90 + 3 = 93
324 = 32 − (2 + 2) = 3222 = 302 = 28
65 + 8 = 65 + (5 + 3) = 65 + 5 + 3 = 70 + 3 = 73
