OpenStudy (anonymous):
because 50 + 50 = 100 51 + 51 = 102
OpenStudy (anonymous):
if its 2(50+1) then its 102
OpenStudy (anonymous):
\[2(50) + 1 \neq 2(50 + 1)\]
OpenStudy (anonymous):
since you are multiplying by 2 , they go up by 2
OpenStudy (anonymous):
you have to follow the rules of operation: parentheses, exponents, multiply/devide, addition/subtraction (PEMDAS) for 2*50+1 you have to MULTIPLY first, then add. if you had added first then they would be equal, but you can't :(
