Answer 1

14065:29+378*207-78279=552

1)14065:29=485

2)378*207=78246

3)485+78246=78731

4)78731-78279=552


22350-258*86-50158:809=

1) 258*86=22188

2) 50158:809=62

3)22188-62=22126

4) 22350-22126=22224

Answer 2

Let's calculate the expressions step by step:

1. (50 - 52) = -2 14065 ÷ 29 = 485 378 × 207 = 78246 -78279 + 78246 = -33

Answer: -33

2. 22350 - (1 * 258) = 22350 - 258 = 22192 50158 ÷ 809 = 62 22192 - 62 = 22130

Answer: 22130

3. 11707 ÷ 23 = 509 4687 ÷ 43 = 109 509 + 109 = 618 618 - 609 = 9

Answer: 9

4. 89 * 805 = 71745 908 * 67 = 60836 71745 - 60836 = 10909 10909 + 2507 = 13416

Answer: 13416

So, the answers are:

1. -33
2. 22130
3. 9
4. 13416
