Solving from left to right.
Signs lies behind a number. This rules is affecting many answers so you have to take it serious and master your number line well.
Solution:
The solution to this question is simple but tricky. Many people always fall into the trap of not using basic mathematical principles and rules such as BODMAS and PEMDAS . BODMAS stands for:B=Bracket, O=Order of operation, D=Divison, M=Multiplication, A=Addition, S=Subtraction while PEMDAS stands for P=Parentheses, E=Exponents, M=Multiplication, A=Addition and S=Subtraction.
So solving this question using BODMAS, we take one step and explain before going to another for better understanding.
10-10×10+10=?
Firstly we start we multiplication that is
-10×10=-100. Remember negative is attached to the second 10. So now we have
10-100+10. Note that negative affects 100 here not 10 because in arithmetic, signs such as +×÷- are attached to number from the left not right.
Secondly we go straight to addition since there is no division sign in the question. If we arrange the work in order of BODMAS, it looks like this 10+10-100=?
20-100=?
-80=?
Answer=-80. Use number line to do your subtraction .
To summarise it , it looks as follows. 10-10×10+10=?
10-10×10+10=?
10-100+10=?
10+10-100=?
20-100=?
-80=?. Means the answer is -80. Confirm it with your calculator and check more similar examples via our blog at: [ Ссылка ]
