Charts to Print, Calculators That Work

The grid

The chart above is text, not a picture of a chart. Find one number down the left side, the other along the top, and read the answer where the row and the column meet. It works either way round: 7 x 8 = 56 and 8 x 7 = 56 land on the same square, which halves how much there is to learn.

The calculator

The box multiplies. It opens on 12 x 12 = 144, the last square of the grid, and the answer changes as you type. Decimals are allowed. It does not divide, so a division is checked backwards: to test that 144 divided by 12 leaves 12, multiply 12 by 12 and see whether you land back on 144.

Two directories

• Multiplication charts and tables – full grids, blank grids to fill in, and single tables from 2 up to 18.
• Calculators – fractions, percentages, ratios and money, one page for each question people actually type.

En français

Ce site existe aussi en français, avec des pages écrites en français et non traduites à la machine : calculatrices et tables. On y trouve entre autres le calcul des mètres cubes et le nombre de jours entre deux dates.

Printing the chart

Wide tables are the thing browsers shrink. Print in landscape, and if the right-hand columns still fall off the sheet, set the print dialogue to fit the page or drop the scale to about 80 per cent. Turn off background graphics and the grid prints in plain black, which is what a photocopier wants.

What to reach for

A whole grid is for reference and for spotting patterns. A single table, the sort you find on the 1 to 12 tables page, is for learning one row at a time. A blank grid is for testing whether the row actually stuck. The three do different jobs, and the blank one is the only one that tells you anything.
