Question

187-(87-40-17)*2(85-53)-(28+16)/428/4*1248/8*1335/5*14

Answer 1

187-(87-40-17)*2=187-(70-40)*2=187-30*2=187-60=127

(85-53)-(28+16)/4 = (32)-(44)÷4 = (-12)÷4= - 3
ИЛИ
(85-53)-(28+16)/4 = (32)-(44)÷4 = 32-11= 21

28÷4×12=7×12=84
48÷8×13=6×13=78
35÷5×14=7×14=98

Answer 2

To solve the expression 187 - (87 - 40 - 17) * 2(85 - 53) - (28 + 16) / 428 / 4 * 1248 / 8 * 1335 / 5 * 14, we need to follow the order of operations, which is often referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Let's break down the expression step by step:

Step 1: Simplify the innermost parentheses Inside the first parentheses, we have (87 - 40 - 17), which equals 30.

Inside the second parentheses, we have (28 + 16), which equals 44.

Step 2: Simplify the remaining parentheses Now we have 187 - 30 * 2(85 - 53) - 44 / 428 / 4 * 1248 / 8 * 1335 / 5 * 14.

To calculate 2(85 - 53), we subtract 53 from 85 and multiply the result by 2, which equals 64.

Step 3: Perform multiplication and division from left to right Now we have 187 - 30 * 64 - 44 / 428 / 4 * 1248 / 8 * 1335 / 5 * 14.

We start with 30 * 64, which equals 1920.

Next, we have 44 / 428, which is approximately 0.1028.

Then, we have 0.1028 / 4, which is approximately 0.0257.

After that, we perform 0.0257 * 1248, which is approximately 32.05.

Next, we have 32.05 / 8, which is approximately 4.0063.

Then, we perform 4.0063 * 1335, which is approximately 5340.43.

Finally, we have 5340.43 / 5, which is approximately 1068.086.

Step 4: Perform subtraction Now we have 187 - 1920 - 1068.086 * 14.

We start with 187 - 1920, which equals -1733.

Then, we perform 1068.086 * 14, which equals 14954.204.

Finally, we have -1733 - 14954.204, which equals -16687.204.

Therefore, the value of the expression 187 - (87 - 40 - 17) * 2(85 - 53) - (28 + 16) / 428 / 4 * 1248 / 8 * 1335 / 5 * 14 is approximately -16687.204.
