What's 5-5× 5+ 5 = ? Answer |
The correct answer to this tricky math quiz would be -15 not 25 or 5. Full solving and explanation below.
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=Division,
M=Multiplication,
A=Addition,
S=Subtraction
PEMDAS stands for:
P=Parentheses,
E=Exponents,
M=Multiplication,
A=Addition and
S=Subtraction.
So , using BODMAS,
5-5×5+5=?
First, multiply -5 × 5= - 25.
Remember in Maths a negative is attached behind a number not in front and if you multiply a negative number with a positive number your result should be negative. This is where you may get confused .
The Quiz will Now be 5 - 25 +5 = ?
Secondly 5+5 = 10.
Quiz will now be 10 - 25=? Recall that with BODMAS addition comes before subtraction and this really means you should deal with all the positive numbers in a question first whether the number comes after a negative number or not.
So, 10 - 25 = ?
-15 = ?
Summarized solving
5-5×5+5=?
Implied 5-25+ 5 = ?
Implied 10-25= ?
Implied -15=?
