Question

-15 - 36 * (-4/9) - 2 : 1/3 по действиям

Answer 1

-15+4х4-2х3
-15+16-6=-5

Answer 2

To solve the expression, follow the order of operations, which is commonly remembered using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition, and Subtraction from left to right):

1. First, perform the operations inside the parentheses, if any.
2. Next, perform any multiplication and division from left to right.
3. Finally, perform any addition and subtraction from left to right.

Now, let's solve the expression step by step:

Step 1: -15 - 36 * (-4/9) - 2 : 1/3

Step 2: -15 + 36 * (4/9) - 2 : 1/3 (Since multiplying by a negative number changes the sign)

Step 3: -15 + 16 - 2 : 1/3 (Evaluate the multiplication inside the parentheses)

Step 4: -15 + 16 - (2 / (1/3)) (Evaluate the division)

Step 5: -15 + 16 - 2 * 3 (Invert the division by multiplying by the reciprocal of 1/3)

Step 6: -15 + 16 - 6 (Perform the remaining multiplication)

Step 7: 1 - 6 (Perform the addition)

Step 8: -5 (Perform the subtraction)

The final result is -5.
