Explanation: For this, we take two different numbers.
Let the first number be [tex]x[/tex] and the second number be [tex]y[/tex]
We use the commutative property, which says that the sum will remain same in whatever way the numbers are written.
Mathematically,
[tex]x+y=y+x[/tex]
From the question,
x = 1
y = 7
Putting this in the commutative property equation, we get:
[tex]1+7=7+1[/tex]
Hence, the sum of both the umber will be same.
