3a2b + 4a3 +b2
What is 3a2b + 4a3 +b2 (You cannot add these terms since the exponents are different.)

What is 195/90?
400
Are integers closed under division. (Give an example to support your answer)
No, integers are not closed under division because 1 divided by 2 is a fraction and fractions are not integers

What is 5.7?
500
Let a @ b be defined as (a+b)/b. Is the operation @ closed for real numbers? Give an example.
No, @ is not closed because if "a" was any real number and b = 0, then a@b would not yield a real number since no real number can have a denominator of zero.
500
The value(s) of a variable that make an equation or inequality true
What is "the solution"
