The opposite of a number is the number that has the same absolute value but has an opposite sign. In this case, the opposite of -12 is 12 because both numbers have the same absolute value of 12, but one is negative and the other is positive.

The given expression (4 ÷ 1 + 4) + 4 can be simplified by following the order of operations, which states that we should perform the division first, then addition. Dividing 4 by 1 gives us 4, and adding 4 to it gives us 8. Finally, adding 4 to 8 gives us the result of 12. Therefore, the correct answer is 12.

The given expression is (4 × 6) − 8. To solve this, we first perform the multiplication, which gives us 24. Then, we subtract 8 from 24, resulting in 16. Therefore, the correct answer is 16.

The given expression -9 + 6 can be solved by subtracting 9 from 6, which gives us -3. Therefore, the correct answer is -3.

The answer to the math problem 112.5 + 2.6 is 115.1.

The given expression is -19 - (-6). When we subtract a negative number, it is the same as adding the positive form of that number. So, -19 - (-6) can be rewritten as -19 + 6. When we add -19 and 6, we get -13. Therefore, the correct answer is -13.

The correct answer is 1 because when you add 11 and -10, you get a sum of 1.

The answer is 0 because when you divide 0 by any number, the result is always 0. In this case, 0 divided by -15, 15, or 1 will all equal 0.

The given expression is (9 - 3) / 3. First, we subtract 3 from 9, which gives us 6. Then, we divide 6 by 3, which gives us 2. Therefore, the correct answer is 2.

When dividing 36 by -6, we are essentially asking how many times -6 can be subtracted from 36. Starting with 36 and subtracting -6 repeatedly, we get 30, 24, 18, 12, 6, and finally 0. Therefore, -6 can be subtracted 6 times from 36, resulting in an answer of -6.

The given expression (1 - 8) × 3 can be simplified by performing the subtraction first, which gives us -7 × 3. Multiplying -7 by 3 gives us -21. Therefore, the correct answer is -21.

The answer to the math problem 299.78 - 287.91 is 11.87. This can be obtained by subtracting the second number from the first number, resulting in the difference of 11.87.

The question asks for 232 raised to the power of 3. To find this, we need to multiply 232 by itself three times. When we do this calculation, we get the answer of 8.

To find the answer to the multiplication problem:

45.6 x 21

Multiply the numbers as follows:

45.6 x 21 = 957.6

So, the answer is 957.6

The expression | -8 | represents the absolute value of -8. The absolute value of a number is its distance from zero on the number line, regardless of its sign. In this case, the distance between -8 and 0 is 8 units. Therefore, the absolute value of -8 is 8.

The expression 15 + 3 - 6 • 2 can be simplified using the order of operations, which states that multiplication should be done before addition or subtraction. So, first, we need to calculate 6 • 2, which equals 12. Then, we can perform the addition and subtraction from left to right, resulting in 15 + 3 - 12 = 18 - 12 = 6. Therefore, the correct answer is 6.

The answer to the math problem 36.5 divided by 4 is 9.125.

The answer to the math problem 365 divided by 2.5 is 146. This can be calculated by dividing 365 by 2.5, which gives us the quotient of 146.

To solve this expression, we follow the order of operations (PEMDAS). First, we perform the addition and subtraction from left to right. -11 - 8 equals -19, then adding 12 gives us -7. Subtracting 9 results in -16, and finally adding 10 gives us -6. Therefore, the answer is -6.

The given expression involves subtraction and addition. First, we need to solve the expression inside the parentheses, which is 9 - 3 = 6. Then, we subtract 6 from 5, which gives us -1. Finally, we add 6 to -1, resulting in 5. Therefore, the answer is 5.

The given expression involves addition, subtraction, and division. According to the order of operations, we should perform the division first. 12 ÷ 4 equals 3. Then, we add -3 and 3, which gives us 0. Finally, we add 0 and 5, resulting in 5.

The given expression involves a combination of division and subtraction. According to the order of operations, we should perform the division first.
(8 ÷ 1 + 7) ÷ 6 - 4 can be simplified as (8 + 7) ÷ 6 - 4, which further simplifies to 15 ÷ 6 - 4.
Next, we perform the division to get 2.5 - 4. Finally, we subtract 4 from 2.5 to get -1.5. Therefore, the correct answer is -1.5.

The given expression can be simplified using the order of operations. First, we perform the addition inside the parentheses: (2 + 3) = 5. Then, we multiply 5 by 5 which gives us 25. Finally, we divide 16 by 4 which equals 4. Adding 25 and 4 gives us the final result of 29.

.

The given expression is |-3| + -2. The absolute value of -3 is 3, so the expression becomes 3 + -2. Adding these two numbers gives us 1 as the answer.

To solve this problem, we need to apply the exponent rule. First, we calculate the square of -6, which is 36. Then, we subtract 62 from 36, resulting in -26. Therefore, the correct answer is 36.

The given expression involves the absolute values of -12 and 4. The absolute value of -12 is 12, and the absolute value of 4 is 4. Adding these absolute values together gives us 16.

When a number is raised to the power of 0, it means that the number is being multiplied by itself 0 times.

For example, 5^0 means multiplying 5 by itself 0 times. So, 5^0 = 1.
