Question

12.42 -(-4.8) how do you get it solved not just the anwser​

Answer 1

Answer:

12.42 -(-4.8) = 17.22

Step-by-step explanation:

1.  The most important thing to note is the double negative signs, separated by the paranthesis.  When 2 signs, numbers, variable, etc... are separated by a ( ) or simply beside each other, such as 2x or 4(6), you would multiply the 2 numbers.

2.  In this equation, note that the negative sign is directly beside the (4.8):

    (-)(-4.8)  This means that you would multiply the negative sign or -1 by the -4,8.  Remember multiplication rules with signs: a negative (-) number x a negative (-) number = a POSITIVE number.

3.  Therefore,  (-)(-4.8)  is looking at the problem as (-) x (-4.8) = +4.8.

4.  Note that at this point, the equation becomes an addition problem:

    12.42 + 4.8 = x

5.  Use your calculator to solve or the CORRECT way of simply lining up the decimals, and, there's your answer:

   12.42 + 4.8 =  17.22
