And notice, I've thrown inĪn extra digit up here. Now we're going to have toĭeal with that 7 right there, which is really a 70. That we don't get confused in our next step. You're putting it in the 2's place, so you still get 20. Multiply this 1, which is really a 10, times 32. This time because you always don't have all this So let's start off with-Īnd I'll start in yellow. Tools to really tackle any multiplication problems. If you google Vedic math, you might find some more cool arithmetic tricks! So we have a running total of 41,690+43 = 41,733 tens so far.įinally, multiply the last digits: 3x8 = 24. So we have a running total of 4,090+79 = 4,169 hundreds so far.Ĭross multiply the last two digits by the last two digits: (2x8)+(3x9) = 16+27 = 43. So we have a running total of 350+59 = 409 thousands so far.Ĭross multiply the first three digits by the first three digits: (5x8)+(2x9)+(3x7) = 40+18+21 = 79. This represents 35 ten-thousands.Ĭross multiply the first two digits by the first two digits: (5x9)+(2x7) = 45+14 = 59. There is a Vedic math trick for multiplying any multi-digit numbers, called vertical and crosswise.įor example, let’s use this trick on the last problem in the lesson, 523 x 798.
