Question

write properties on integers under subtraction​

Answer 1

Step-by-step explanation:

Integers are closed under addition, i.e. for any two integers a and b, a + b is an integer. Ex: 3 + 4 = 7; (– 9) + 7 = – 2. Closure property under subtraction: Integers are closed under subtraction, i.e. for any two integers a and b, a – b is an integer.

Answer 2

Answer:

Integers are closed under subtraction, i.e. for any two integers a and b, a – b is an integer. Ex: (– 21) – (– 9) = (– 12); 8 – 3 = 5. Closure property under multiplication: Integers are closed under multiplication, i.e. for any two integers a and b, ab is an integer.
