{| style="margin:auto; table-layout:fixed; border-collapse:collapse;" You can't take three from two, Two is less than three, So you look at the four in the eights place. Now that's really four eights, So you make it three eights, Regroup, and you change an eight to eight ones And you add 'em to the two, And you get one-two base eight, Which is ten base ten, And you take away three, that's seven. Ok?

But don't panic! Base eight is just like base ten really - if you're missing two fingers! Shall we have a go at it? Hang on…

Now instead of four in the eights place You've got three, 'Cause you added one, That is to say, eight, to the two, But you can't take seven from three, So you look at the sixty-fours...

''"Sixty-four? How did sixty-four get into it?" I hear you cry!'' Well, sixty-four is eight squared, don't you see? Well, you ask a silly question, you get a silly answer!

From the three, you then use one To make eight ones, You add those ones to the three, And you get one-three base eight, Or, in other words, In base ten you have eleven, And you take away seven, And seven from eleven is four! Now go back to the sixty-fours, You're left with two, And you take away one from two, And that leaves?

Now, let's not always see the same hands! ''One, that's right. Whoever got one can stay after the show and clean the erasers.''

Hooray for New Math, New-hoo-hoo Math! It won't do you a bit of good to review math. It's so simple, So very simple, That only a child can do it!
