Chapter: 4th Maths : Term 2 Unit 2 : Numbers
Multiply by 1, 0
The product of one and any number is the number itself. The product of zero and any number is zero.
Multiply by 1
$$10 \times 1 = 10$$
$$7 \times 1 = 7$$
$$136 \times 1 = 136$$
$$9936 \times 1 = 9936$$
$$2000 \times 1 = 2000$$
$$789 \times 1 = 789$$
The product of one and any number is the number itself.
Multiply by 0
$$10 \times 0 = 0$$
$$6 \times 0 = 0$$
$$276 \times 0 = 0$$
$$7936 \times 0 = 0$$
$$3000 \times 0 = 0$$
$$675 \times 0 = 0$$
The product of zero and any number is zero.
Order of multiplication
$$4 \times 6 = 24 = 6 \times 4$$
$$136 \times 15 = 2040 = 15 \times 136$$
$$1000 \times 9 = 9000 = 9 \times 1000$$
$$796 \times 9 = 7164 = 9 \times 796$$
$$1326 \times 6 = 7956 = 6 \times 1326$$
$$26 \times 24 = 624 = 24 \times 26$$
The product of two number does not change, if we interchange the order of numbers.
