1)5-(-6:3)-(8:5)=5,4

2)52:4-(-45:6)+(-11:5)=18,3

Answer 3

To evaluate the given expressions, we'll perform operations according to the order of operations (also known as PEMDAS/BODMAS) which stands for Parentheses/Brackets, Orders (exponents and roots), Division and Multiplication (from left to right), and Addition and Subtraction (from left to right).

Let's solve each expression step by step:

1. 5-(-6;3)-(8;5) To simplify the expression, we'll start by resolving the subtraction inside the parentheses.

   -6;3 = -6 8;5 = 8

   Now we have: 5 - (-6) - 8

   Since we have a double negative, we can simplify it as follows: 5 + 6 - 8 = 11 - 8 = 3

   Therefore, 5-(-6;3)-(8;5) simplifies to 3.

2. 52;3-(-45;6)+(-11;5) Again, we'll begin by simplifying the subtraction inside the parentheses.

   -45;6 = -45 -11;5 = -11

   Now we have: 52;3 - (-45) + (-11)

   To evaluate 52;3, we'll divide 52 by 3: 52 ÷ 3 ≈ 17.3333

   Now the expression becomes: 17.3333 - (-45) + (-11)

   Since we have a double negative, we can simplify it as follows: 17.3333 + 45 - 11 = 62.3333

   Therefore, 52;3-(-45;6)+(-11;5) simplifies to 62.3333.

Final results:

1. 5-(-6;3)-(8;5) = 3
2. 52;3-(-45;6)+(-11;5) ≈ 62.3333
