Question

how come 2*50+1=101 but 51*2=102

Answer 1

because

50 + 50 = 100

51 + 51 = 102

Answer 2

if its 2(50+1)
then its 102

Answer 3

\[2(50) + 1 \neq 2(50 + 1)\]

Answer 4

since you are multiplying by 2 , they go up by 2

Answer 5

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 :(
