Answer 2

Expression 1: 336:(178-15*10)

To evaluate this expression, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

Let's break down the expression step by step:

1. First, we need to evaluate the expression inside the parentheses: 178-15*10. - 15 multiplied by 10 equals 150. - Subtracting 150 from 178 gives us 28.

2. Now, we can substitute the result back into the original expression: 336:28. - Dividing 336 by 28 gives us 12.

Therefore, the value of the expression 336:(178-15*10) is 12.

Expression 2: 814:37

To evaluate this expression, we simply need to divide 814 by 37.

Dividing 814 by 37 gives us approximately 22.054.

Therefore, the value of the expression 814:37 is approximately 22.054.

Expression 3: 754:58

To evaluate this expression, we need to divide 754 by 58.

Dividing 754 by 58 gives us approximately 13.000.

Therefore, the value of the expression 754:58 is approximately 13.000.

Expression 4: 900:75*38+144-49*12

To evaluate this expression, let's break it down step by step:

1. First, we need to perform the multiplication: 75*38 and 49*12. - 75 multiplied by 38 equals 2,850. - 49 multiplied by 12 equals 588.

2. Next, we need to perform the division: 900:75. - Dividing 900 by 75 gives us 12.

3. Now, we can substitute the results back into the original expression: 12*38+144-588. - Multiplying 12 by 38 gives us 456. - Subtracting 588 from 456 gives us -132. - Adding 144 to -132 gives us 12.

Therefore, the value of the expression 900:75*38+144-49*12 is 12.

Expression 5: (739+245):82+31*29

To evaluate this expression, let's break it down step by step:

1. First, we need to perform the addition inside the parentheses: 739+245. - Adding 739 and 245 gives us 984.

2. Next, we need to perform the division: 984:82. - Dividing 984 by 82 gives us 12.

3. Now, we can substitute the result back into the original expression: 12+31*29. - Multiplying 31 by 29 gives us 899. - Adding 12 to 899 gives us 911.

Therefore, the value of the expression (739+245):82+31*29 is 911.

Expression 6: 13*(469-398)-42*21:63

To evaluate this expression, let's break it down step by step:

1. First, we need to perform the subtraction inside the parentheses: 469-398. - Subtracting 398 from 469 gives us 71.

2. Next, we need to perform the multiplication: 13*(469-398) and 42*21. - 13 multiplied by 71 equals 923. - 42 multiplied by 21 equals 882.

3. Now, we can perform the division: 882:63. - Dividing 882 by 63 gives us 14.

4. Finally, we can substitute the results back into the original expression: 13*(469-398)-42*21:63. - Multiplying 13 by 71 gives us 923. - Subtracting 923 from 882 gives us -41. - Dividing -41 by 63 gives us approximately -0.651.

Therefore, the value of the expression 13*(469-398)-42*21:63 is approximately -0.651.

Regarding the notation, you can either write the steps below the example or provide the solution directly after the example. Both methods are acceptable as long as the steps and the solution are clearly presented.
