Question

83+45-68•5:3-46+19-3

Answer 1

Пошаговое объяснение:

1) 68 * 5 = 340

2) 340 : 3 = 340/3 = 113 1/3

3) 83 + 45 = 128

4) 128 - 113 1/3 = 127 3/3 - 113 1/3 = 14 2/3

5) 14 2/3 - 46 = 14 2/3 - 45 3/3 = -31 1/3

6) -31 1/3 + 19 = -31 1/3 + 18 3/3 = -30 4/3 + 18 3/3 = -12 1/3

7) -12 1/3 - 3 = -15 1/3

Answer 2

To solve the expression 83+45-68*5/3-46+19-3, we need to follow the order of operations, which is commonly remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break down the expression step by step:

Step 1: Perform multiplication and division from left to right. 68*5/3 = 340/3 = 113.33

Now the expression becomes: 83+45-113.33-46+19-3

Step 2: Perform addition and subtraction from left to right. 83+45 = 128 128-113.33 = 14.67 14.67-46 = -31.33 -31.33+19 = -12.33 -12.33-3 = -15.33

Therefore, the value of the expression 83+45-68*5/3-46+19-3 is approximately -15.33.
