You would need to follow the order of operations

5 * 2 would be done first, then it would follow the normal left to tight fashion

5 * 2 = 10 then you would do 25 -10 = 15 + 5 would be 20

Thanks!

Order of operations are:

  1. Parenthesis
  2. division and multiplication (from left to right)
  3. Addition and Subtraction (from left to right)

here's a link to Khan academy where they cover them. https://www.khanacademy.org/math/pre-algebra/pre-algebra-arith-prop/pre-algebra-order-of-operations/v/introduction-to-order-of-operations

Your question is very vague, what exactly do you need help with?

I need help with finding the value of binary operators. For example: Find the value of x: let x = 25 - 5 * 2 + 5
