Answer 2

38. a) 0 + 8 - 3: To solve this expression, we follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

There are no parentheses or exponents in this expression, so we move on to multiplication and division. Again, there are none in this expression.

Finally, we proceed with addition and subtraction. Starting from the left, we have 0 + 8 which equals 8. Then, we subtract 3 from 8 to get a final result of 5.

So, 0 + 8 - 3 = 5.

39. a) (+16) + 4; 6) (+16) - 4; To solve these expressions, we follow the order of operations.

For the first expression, we have (+16) + 4. Since there are no parentheses, we move on to addition and subtraction. Adding 16 and 4, we get a result of 20.

For the second expression, we have (+16) - 4. Again, there are no parentheses to deal with, so we move on to subtraction. Subtracting 4 from 16, we obtain 12.

So, (+16) + 4 = 20 and (+16) - 4 = 12.

b) 0 - 8 + 3; To solve this expression, we follow the same order of operations.

Starting with subtraction, we have 0 - 8, which gives us -8. Then, we add 3 to -8 to obtain a final result of -5.

Therefore, 0 - 8 + 3 = -5.

r) 0 - 8 - 3; Using the order of operations, we proceed with subtraction. Subtraction has left-right associativity, which means we start with 0 - 8 and then subtract 3 from the result.

0 - 8 equals -8, and then subtracting 3 from -8 gives us a final result of -11.

Thus, 0 - 8 - 3 = -11.

a) 0 + 3 - 8; Following the same order of operations, we start with addition. Adding 0 and 3, we get 3. Then, we subtract 8 from 3 to obtain a final result of -5.

Hence, 0 + 3 - 8 = -5.

e) 0 - 3 + 8. Using the order of operations, we begin with subtraction. Subtracting 3 from 0 yields -3. Then, we add 8 to -3 to get a final result of 5.

Therefore, 0 - 3 + 8 = 5.
