(154+246)-400 350:(785-435) 740*(1000:100):100 (856-234-621)*75 (345+763):(12*7-83) (546+894):10-72*2​

Answer 1

Відповідь:

(154+246)-400=0

350:(785-435)=1

740*(1000:100):100=74

(856-234-621)*75 =75

(345+763):(12*7-83) =1108

(546+894):10-72*2​=0

Answer 2

Let's break down each of these mathematical expressions step by step:

1. (154 + 246) - 400 = 400 - 400 = 0

2. 350 : (785 - 435) = 350 : 350 = 1

3. 740 * (1000 : 100) : 100 = 740 * 10 : 100 = 740 : 100 = 7.4

4. (856 - 234 - 621) * 75 = (856 - 855) * 75 = 1 * 75 = 75

5. (345 + 763) : (12 * 7 - 83) = 1108 : (84 - 83) = 1108 : 1 = 1108

6. (546 + 894) : 10 - 72 * 2 = 1440 : 10 - 144 = 144 - 144 = 0

So, the results of these mathematical expressions are as follows:

1. 0
2. 1
3. 7.4
4. 75
5. 1108
6. 0
