Answer 1

Answer:

in the given option there is nothing about number but if we want to understand closure property we have to get understand it

1. closure property under addition

it is that if we change the place of numbers in addition then the answer will not change as the rule is a + b = b + a . for example =

2 + 3 = 3 + 2 = 5

2. closure property under multiplication

it is that if we change numbers in multiplication then the value or answer will not change as the rule is a * b = b * a . for example =

2 * 3 = 3 * 2

and now in subtraction and divide there is change because if we divide or subtract the question and we change the number then their will answer in -

for example =

2 - 3 = -1 and 3 - 2 = 1

10 / 5 = 2 and 5 / 10 = 0.5
