(2 + 3) / 4 = 5/4.
Therefore, the numerical expression 1/2 - (-3/4) is equal to 5/4.
To evaluate the numerical expression -5.45 + 4.12 - 8.66, follow these steps:
Step 1: Start with the first number, -5.45.
Step 2: Add the next number, 4.12, to the result from step 1: -5.45 + 4.12 = -1.33.
Step 3: Subtract the final number, 8.66, from the result from step 2: -1.33 - 8.66 = -10.99.
Therefore, -5.45 + 4.12 - 8.66 equals -10.99.
To evaluate the numerical expression -5.45 + 4.12 - 8.66, you will need to perform the addition and subtraction operations in the given order.
Step 1: Start with the first two numbers, -5.45 and 4.12. Add them together.
-5.45 + 4.12 = -1.33
Step 2: Take the result from step 1 (-1.33) and subtract the third number, 8.66.
-1.33 - 8.66 = -9.99
So, the numerical expression -5.45 + 4.12 - 8.66 evaluates to -9.99.
