In this post,we will talk about one of the mathematics formulas.
The formula that we will talk about is the formula of + and -
Let's start.
1. 12-10-3+5-7-4-6+10+2
First of all we will separate the digits of minus(-) and Plus(+) from each other.
To know it in details,imagine that all the digits of plus(+),we have to give and all the digits of minus(-),we are going to take.
Now,we will separate + and - digits from each other.
12-10-3+5-7-4-6+10+2
12+5+10+2-10-3-7-4-6
Now we will cut +10 and -10 with each other.
Because +10 we are going to take from someone and -10 we are going to give to someone. That's why we will cut them with each other.
Now,we will plus all the digits of Plus (+)and minus(-) separately. Therefore:-
=12+5+2-3-7-4-6
Then Plus(+)'s numbers become= +19 and the minus's = -20
=+19-20 = -1
Answer is - 1 because -20 is big number.
And we always we always write the sign of big number.
Here is the solved sum:-
12-10-3+5-7-4-6+10+2
12+5+10+2-10-3-7-4-6
We cut +10 and -10 with each other.
Therefore = (12+5+2)(-3-7-4-6)
= (19) (-20)
= -1 Answer
Here is another example :-
2. 5+15-9+10-8-2
We will separate all the numbers of + and - like we did before.
Therefore
= 5+15+10-9-8-2
Now,numbers of plus are 25 and the numbers of minus are 19.
Therefore , 25-19 = 6 Answer.
