Negative Plus a Positive Number
Introduction :
Generally the plus and minus signs (+ and -) are the mathematical symbols used to represent the notions of positive and negative numbers as well as the operations of addition and subtraction. These have been used extended too many other meanings, more or less analogous. Plus and minus are Latin terms meaning as "more" and "less", respectively (source Wikipedia).
Rules for a negative plus a positive number:
When we add a negative plus a positive number the subtraction process can be done.
The answer sign is based on the biggest number sign. If the biggest number sign having negative means the answer will be negative and vice versa.
Plus sign:
The positive sign is one of the binary operators that indicate addition operations, such as 2 + 3 = 5. It can also serve as a unary operators that leave its operand unchanged
Therefore +x means the same as x.
Minus sign:
In mathematical operations negative sign has perform three operations:
The subtraction operator:
*the negative sign is one of the binary, as in 5 - 3 = 2. Subtraction is just opposite of an addition.
*the instance of negative 5 can also be written as – (5)
*when the variable is changed as negative then the value is also termed as negative. For example, if x is 3, then -x are -3, but if x is -3, then -x is 3. Similarly, - (-2) is equal to 2.
Example problems:
Adding negative number plus positive number
If a number is represented without any sign then it is represented as positive number.
Example: - 15 is really +5
The adding negative number and positive number is just simply as subtraction.
Example: -15 + 5 = -10
The above example is expressed as "Positive 5 is subtracted with Negative 15 equals negative 10"
It also could written it as (-15) + (5) = (-10)
Ex 1: Solve the problem: -5 + 10
Sol : In this example we need to add -5 with 10
here 10 is greater than 5, so the result will be in positive sign.
-5+10 = + 5
Ex 2: solve the problem -12 + 6
Sol : In the example the greater value in - sign , so the result will be in - sign.
-12 + 6= - 6
