How do you simplify #95.4 + (-39.37) +4.6#?

Answer 1

#60.63#

There are 3 separate terms, so we can just add them without any worries about order of operations. Note that the middle term just becomes -39.37.

Work from left to right, or do the two additions first, then subtract the middle term.

#95.4 - 39.37 +4.6 = 95.4 + 4.6 -39.37 = 60.63#

NOTE: It is NOT equal to

#95.4 - (39.37 + 4.6)# because in this case both the 39.37 and the 4.6 are being subtracted. This will give a WRONG answer of 51.43.
