Put the 1 of the slide under the number 2 on the top ruler. Look along to 8 on the slide. Read the answer 16 on the top ruler. * With the slide in this position you can see all the 2 times tables! * eg. To multiply 12 * 30. We multiply 1.2 by 3.0 and adjust the decimal places. Put the 1 of the slide under the number 1.2 on the top ruler. Look along to 3 on the slide. Read the answer 3.6 on the top ruler. The answer is 360 after we adjust the decimal places. Actually you can also choose to put the 10 (rather than the 1) on the slide under the number to multiply by on the rule. For 9 x 8 put the 10 on the slide under the 9 on the rule and read the answer above the 8 on the slide. Of course you can use a slide rule to divide too.
