Answer 2

Let's solve the equations step by step:

1. 870 - (36 - 9) + 23:

   First, solve the inner parentheses: 36 - 9 = 27.

   Then, subtract the result from 870: 870 - 27 = 843.

   Finally, add 23 to the result: 843 + 23 = 866.

2. (240 - 120) : 3 + 9:

   First, subtract 120 from 240: 240 - 120 = 120.

   Then, divide the result by 3: 120 / 3 = 40.

   Finally, add 9 to the result: 40 + 9 = 49.

3. 870 - 36 - (9 + 23):

   First, subtract 36 from 870: 870 - 36 = 834.

   Then, add 9 and 23: 9 + 23 = 32.

   Finally, subtract the result from 834: 834 - 32 = 802.

4. 240 - 120 : (3 + 9):

   First, add 3 and 9: 3 + 9 = 12.

   Then, divide 120 by 12: 120 / 12 = 10.

   Finally, subtract the result from 240: 240 - 10 = 230.

So, the results of the given expressions are:

• 870 - (36 - 9) + 23 = 866
• (240 - 120) : 3 + 9 = 49
• 870 - 36 - (9 + 23) = 802
• 240 - 120 : (3 + 9) = 230
