Arrange the expressions on the cards in ascending order: four multiplied by six, 77 take away 73, 117 take away 117, two multiplied by seven multiplied by three.

The question asks us to arrange the expressions on the cards in ascending order, which means from smallest to greatest. Four multiplied by six is 24. 77 minus 73 is four. 117 take away 117 is zero. Two multiplied by seven is 14. 14 multiplied by three, three tens make 30 and four multiplied by three is 12; 30 plus 12 equals 42.

We can see that zero is the smallest number so if we’re going to arrange the cards in ascending order we need to start with the one which is smallest in value. The next smallest number is four, so we can write the expression 77 take away 73 next.

The next smallest answer is 24, so we can write four multiplied by six next. And the greatest answer was 42. The expressions arranged in ascending order are 117 take away 117, 77 take away 73, four multiplied by six, and two multiplied by seven multiplied by three.
