1 over 4 − (−5 over 8)

To subtract fractions, we need to find a common denominator.

The common denominator of 4 and 8 is 8.

So, 1 over 4 is equivalent to 2 over 8 (multiplying the numerator and denominator by 2).

Now, we can subtract fractions:

2 over 8 minus (-5 over 8) is equal to (2 + 5) over 8.

2 + 5 = 7

Therefore, the answer is 7 over 8.

260 − (−45) − 45

To solve this expression, we first simplify the subtraction of negative numbers.

260 minus (-45) is the same as 260 plus 45.

260 + 45 = 305

Now, we subtract 305 minus 45.

305 - 45 = 260

Therefore, the final result is 260.

186 − (−72)

To solve this expression, we simplify the subtraction of negative numbers.

186 minus (-72) is the same as 186 plus 72.

186 + 72 = 258

Therefore, the final result is 258.

10.82 − 9.99
