Question

Evaluate for the following values of y

Answer 1

The procedure here, for each "evaluation", is broken down into three parts:

1. to get rid of the minus signs,

2. to solve the resulting sum as usual (for the decimal number case), and

3. adding a minus to the result of the second step.

Note: This can be done for the values of y are all negative and -15.85 is negative.

y=-63.06) Step one gives us:

$15.85+63.06$

Step two gives us:

$15.85+63.06=78.91$

And finally, step three gives us:

$-78.91$

y=-84.703) Step one gives us:

$15.85+84.703$

Step two gives us:

$15.85+84.703=100.553$

And step three gives us:

$-100.553$

y=-8.115) Step one gives us:

$15.85+8.115$

Step two gives us:

$15.85+8.115=23.965$

And step three gives us:

$-23.965$

Comment: Don't forget to add the minus sign at the end.
