| I used a sort of in-line multiplication, working from left the right. Type the previous answer in the the answer bar, multiply the leftmost digit by the number (carrying any extra digits over to the left), move to the next digit (if you get a two digit answer, add it in appropriately). It works great:
8^8 = 16777216
8^9 = 16777216?
8^9 = 86777216?
8^9 = 128777216? (6x8 = 48, 8 + 4 = 12)
8^9 = 133677216? (7x8 = 56, 28 + 5 = 33)
8^9 = 134167216? (7x8 = 56, 36 + 5 = 41)
8^9 = 134216216? (7x8 = 56, 16 + 5 = 21)
8^9 = 134217616? (2x8 = 16, 6 + 1 = 7)
8^9 = 134217686?
8^9 = 134217728 (6x8 = 48, 68 + 4 = 72)
It works great moving along in the answer bar and typing... if you used another method without much luck and still have your wits about you, try this one! It worked well for me... |
