Date: 11/24/96 at 14:39:50 From: Doctor Sarah Subject: Re: Multiplication tables Hi there - I've made up a table for you that goes through 12x12 - I hope that's enough. 2 3 4 5 6 7 8 9 10 11 12 2 4 6 8 10 12 14 16 18 20 22 24 3 6 9 12 15 18 21 24 27 30 33 36 4 8 12 16 20 24 28 32 36 40 44 48 5 10 15 20 25 30 35 40 45 50 55 60 6 12 18 24 30 36 42 48 54 60 66 72 7 14 21 28 35 42 49 56 63 70 77 84 8 16 24 32 40 48 56 64 72 80 88 96 9 18 36 36 45 54 63 72 81 90 99 108 10 20 30 40 50 60 70 80 90 100 110 120 11 22 33 44 55 66 77 88 99 110 121 132 12 24 36 48 60 72 84 96 108 120 132 Do you notice any patterns? How about in the 2's column? Look at the horizontal and vertical rows for the 10's and the 11's - they're pretty easy to see. Have you seen our archive of questions and answers for Dr. Math? (The URL is at the bottom of this message.) There's a suggestion for learning multiplication tables that you should really look at there: http://mathforum.org/dr.math/problems/unknown2.5.96.html My grandfather was one of the first surveyors of the Mississippi River. He was an engineer and floated down the river on a raft. I've been told that he was famous for playing the harmonica and knowing his multiplication tables through 20x20. When you have learned your tables through the 12's, you'll probably be able to make up a table for the higher numbers yourself! I think the only real way to learn your multiplication tables is to practice a lot. They are a really good thing to know, though - you will use them all the time, even when you're grown up! -Doctor Sarah, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
