Multiplication challenge 1st December

Boys and girls, your challenge for this week is to choose 3 digits between 0-9 and create the 6 possible multiplication sums for them and mentally calculate the answer.

For example if I chose 3, 4 & 9 the possibilities are:

3 x 49 = 147         3 x 94 = 282

4 x 39= 156             4 x 93= 372

9 x 34 = 306            9x 43= 387

Have fun and I look forward to discussing your methods.
