Question

⇒a+b-c=? (a, b, c ∈ N)

Answer 1

{ab = 13,
{bc = 9;
a, b, c ∈ N ⇒ a = 13, b = 1, c = 9
a + b - c = 14 - 9 = 5

Answer 2

In the given expression, "a+b-c," the symbols a, b, and c are represented as natural numbers (positive integers). Since there is no specific value provided for a, b, or c, we cannot determine the exact numerical result of the expression.

If you have specific values for a, b, and c, you can substitute them into the expression and perform the arithmetic to find the result. For example, if a = 5, b = 8, and c = 3, then:

a + b - c = 5 + 8 - 3 = 13 - 3 = 10

But without actual values for a, b, and c, we cannot calculate the final result.
