60005+(36006-28097)         100105-(87007-679)       400+80/4*5       800-640/2/4   помогите решить!!!

Answer 1

To solve the given expression, let's break it down step by step:

1. 60005 + (36006 - 28097): - First, subtract 28097 from 36006: 36006 - 28097 = 7909. - Then, add 60005 to the result: 60005 + 7909 = 67914.

2. 100105 - (87007 - 679): - First, subtract 679 from 87007: 87007 - 679 = 86328. - Then, subtract the result from 100105: 100105 - 86328 = 13777.

3. 400 + 80 / 4 * 5: - First, divide 80 by 4: 80 / 4 = 20. - Then, multiply the result by 5: 20 * 5 = 100. - Finally, add 400 to the result: 400 + 100 = 500.

4. 800 - 640 / 2 / 4: - First, divide 640 by 2: 640 / 2 = 320. - Then, divide the result by 4: 320 / 4 = 80. - Finally, subtract 80 from 800: 800 - 80 = 720.

Therefore, the solution to the given expression is: 60005 + (36006 - 28097) = 67914, 100105 - (87007 - 679) = 13777, 400 + 80 / 4 * 5 = 500, 800 - 640 / 2 / 4 = 720.

I hope this helps! Let me know if you have any further questions.
