<span>Subtraction exhibit a property of closure over the set of real numbers because if you subtract two numbers from the real numbers set, the result will still be a real number.
Example:
Let RS be a set of real numbers.
RS = {1, 2, 3}
Suppose I get 3 and subtract 1, 3 - 1, the result is 2 which is a real number. We can try a non-commutative 1 - 3 and yet it will still give us a real number which is -2.
</span><span>Subtraction is non-commutative because if we interchange numbers in subtraction, the result will either be positive or negative.
Example:
3 - 1 = 2. The answer is 2; but we can not say this is true for 1 - 3 because it will yield -2.

Answer:
v=15z-pz
Step-by-step explanation:
Solve for v by simplifying both sides of the equation, then isolating the variable.
Arranged in descending order means the terms are arranged in the order of the exponent, from the largest to the smallest. the exponent is the little number up right to y, 3y^4+6y^3+2Y^2-5yso the third term is 2y^2

Answer:
Nt=10 (m=4,n=6)
Step-by-step explanation:
we have that m = amount of time used by the large washing machine to wash a load of clothes and n = amount of time used by the small washing machine to wash a load of clothes, so
Nt=m+n=10
where Tt = time frame, Tpm= m' time frame, Tpn = n' time frame and Nt = total number of charges
