Write a multiplication fact for each of the repeated additions:
13+13+13+13+13=____
____×____=____
65
5×13=65
We know, that multiplication is repeated addition.
Here 13 is repeated 5 times,
Then, 13+13+13+13+13=65
We can write multiplication fact for each of the repeated additions as 5×13=65
40+40=________×______=______
Statement 1: 13×(−17)=17×(−13)
Statement 2: The multiplication operation holds true for commutative property.
