Times Tables 1 to 12

What is in this deck

With this deck you learn every multiplication fact from 1 to 12 and the division facts that come with them.

Every times table fact is worth two: seven eights and eight sevens are the same number, which halves what there is to learn. That is why this deck has 199 cards and not three hundred.

Each multiplication appears once, in its smaller form, with the trick for that row on the back. Fours are doubled twice. Nines are ten times minus one time, and the digits of every answer in that row add to nine. Elevens up to nine simply repeat the digit.

Then the same facts as division, because that is the direction they are needed in when a fraction has to be reduced or a total shared out. A fact known only one way round is known half as well.

The categories decide what comes up: start with “Dividing by eight” alone and add the rest when you are ready.

What you learn

Learning with Qardbox

You see a card, you think, you turn it over and say whether you knew it. A round asks nothing more of you, and how the app works out the next date from that is on the page about FSRS-6.

What sits comes back less often, what wobbles comes back soon. You set a daily goal, and when nothing is due the app tells you exactly that instead of inventing work for you. How a round goes is shown on the learning page.

Everything stays on your device. No account, no sign-up, no ads. After the purchase the deck sits in your library like any other subject and can be studied, reordered and extended just like your own.

What it costs, and what it doesn’t

Qardbox itself costs nothing, and it stays that way. Every function is there from the start, with no subscription, no ads and no tiers; what that rests on is on the page about what it costs.

Your own cards stay unlimited, and decks from friends or from the family you read in without a limit, from a file as well. You do not need this deck in order to learn with Qardbox.

It is a shortcut: 199 checked cards for €1.29, once, with Family Sharing. The work you would otherwise do is already done. The App Store shows the price in your currency.
