Answer:

Step-by-step explanation:

1. Use acronym PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction) to determine the order of operations.

2. Since there are no parentheses or exponents, multiply first:

4*5=20

3. Now, the expression reads 20+-4. Adding a negative is the same as subtracting that value.

20-4=16

Hope this helps!!
