63000-(36000-12000) ÷4

To solve this expression, we need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).

Step 1: Simplify the expression inside the parentheses first. 36000 - 12000 = 24000

Step 2: Divide the result by 4. 24000 ÷ 4 = 6000

Step 3: Subtract the result from 63000. 63000 - 6000 = 57000

Therefore, the value of the expression 63000-(36000-12000) ÷ 4 is 57000.
