To find the result of −123.45−(−234.76), we can use the additive inverse.

The additive inverse of a number is the number that when added to the original number, gives a sum of zero.

In this case, the additive inverse of −234.76 is 234.76 because -234.76 + 234.76 = 0.

So, −123.45−(−234.76) can be rewritten as −123.45 + 234.76.

Now, we can add these two numbers together:

−123.45 + 234.76 = 111.31.

Therefore, the answer is 111.31.

To subtract 20.5 from 16, we can start by representing 16 on a number line.

A number line ranges from negative 4 to 16 in increments of 1. A solid line with dots on both ends is drawn on the number line, ranging from negative 4 to 16.

To subtract 20.5, we move 20.5 units to the left of 16 on the number line.

Therefore, the solution is -4.5.
