What is arithmetic?

Statements execute as mathematical expressions. In arithmetic mathematics deals with various statements, progressions, sequences etc.

Here,
      ⇒2n+1=21
          2n=21-1
          2n=20
           n=20/2
           n=10

Thus, the value of n in equation 2n+1=21 is 10.

M+-2/3=-1/3 what is m?

Answers

m + - (2)/(3) = - (1)/(3) \n \n m -  (2)/(3) = - (1)/(3) \ / \ simplify \n \n m = - (1)/(3) + (2)/(3) \ / \ add \  (2)/(3)  \ to \ each \ side \n \n m =  (1)/(3) \ / \ simplify \n \n Answer: \fbox {m = 1/3} \ or \ \fbox {m = 0.3333}
M+ -2/3= -1/3
⇒ M+ (-2/3)= -1/3
⇒ M= -1/3+ 2/3
⇒ M= 1/3

Final answer: M= 1/3~
