Answer 3

To solve this expression, we follow the order of operations, which is commonly remembered by the acronym PEMDAS (parentheses, exponents, multiplication and division, addition and subtraction).

The expression 139-23 is not directly involved in the rest of the expression, so we can calculate it first:

139-23 = 116

Now, we can simplify the rest of the expression:

3,8 + 4,35 * 1,8

Multiplication comes before addition, so we first calculate:

4,35 * 1,8 = 7,83

Now, we can add 3,8 and 7,83:

3,8 + 7,83 = 11,63

Therefore, the final result of the expression is:

116,63
