## What is the 3 times table trick?

Have a look at these timesavers. There’s a clever trick you can use to find out if a number is in the 3 × table. Add up the digits of the number you want to find out about – this is called finding the digit sum. If the digit sum is 3, 6, or 9, then you know that it’s in the 3 × table.

What is the table of 1000?

The repeated addition of 1000 is the multiplication table of 1000. For example, 1000 + 1000 + 1000 = 3 × 1000 = 3000….Table of 1000 up to 10.

1000 × 3 = 3000 1000 × 8 = 8000
1000 × 4 = 4000 1000 × 9 = 9000
1000 × 5 = 5000 1000 × 10 = 10000

What is the hardest multiplication sum?

The hardest multiplication was six times eight, which students got wrong 63% of the time (about two times out of three). This was closely followed by 8×6, then 11×12, 12×8 and 8×12.
