Question

Памогите. Вычесли наиболее удобным способом; (834 + 98)- 234 =? 781 - ( 56+ 681)=? 592 + ( 294 + 108)=? 75+139+25+61=? 2•(5•69)=? (5•27)•6=?

Answer 1

(834-234)+98=698
(781-681)+56=156
(592+108)+294=994
(139+61)+(75+25)=300
(2*5)*69=690
(5*6)*27=810

Answer 2

(834-234)+98=698
(781-681)+56=156
(592+108)+294=994
(75+25)+(139+61)=300
(2*5)*69=690
(5*6)*27=810

Answer 3

Calculations

Let's solve the given mathematical expressions step by step:

1. (834 + 98) - 234 = ? - To solve this, we first add 834 and 98, and then subtract 234 from the sum. - The result is: (834 + 98) - 234 = 698

2. 781 - (56 + 681) = ? - Here, we add 56 and 681, and then subtract the sum from 781. - The result is: 781 - (56 + 681) = 44

3. 592 + (294 + 108) = ? - We add 294 and 108, and then add the sum to 592. - The result is: 592 + (294 + 108) = 994

4. 75 + 139 + 25 + 61 = ? - Simply add all the numbers together. - The result is: 75 + 139 + 25 + 61 = 300

5. 2 • (5 • 69) = ? - First, perform the operation inside the parentheses, then multiply by 2. - The result is: 2 • (5 • 69) = 690

6. (5 • 27) • 6 = ? - Multiply 5 and 27, then multiply the result by 6. - The result is: (5 • 27) • 6 = 810
