Answer:
-1.3
Explanation:
you can ignore this + in this question. In mathematics we write it as
4.6 + -5.9
It says + a negative number, which is almost like saying "I am going outside with without my jacket..." And that means I go outside without it. The same goes here...
In mathematics the rule is (+ * - ) = -
4.6 - 5.9 = -1.3
EXTRA:
Whenever you are dealing with negative numbers, you can think of the numbers as if it is about temperatures...
Suppose you have a temperature of 4.6 degrees and then it gets colder with an "amount" of 5.9 degrees. This of course accounts for a negative temperature of 1.3 degrees... ( because 4.6 + 1.3 = 5.9)
So - 1.3
