Question

a) b) 6,24:0,4+7,65-20-1000 0,01-5²=
​

Answer 1

a) b) 6,24:0,4+7,65-20-1000 0,01-5²=

To solve this expression, we can break it down step by step:

Step 1: Calculate the division 6,24:0,4

6,24 ÷ 0,4 = 15,6

Step 2: Calculate the subtraction 15,6 + 7,65

15,6 + 7,65 = 23,25

Step 3: Calculate the next subtraction 23,25 - 20

23,25 - 20 = 3,25

Step 4: Calculate the final subtraction 3,25 - 1000

3,25 - 1000 = -996,75

Step 5: Calculate the exponentiation 5²

5² = 5 * 5 = 25

Step 6: Calculate the subtraction 0,01 - 25

0,01 - 25 = -24,99

So, the final result is -996,75 - 24,99 = -1021,74
