arithmetic

Significance and counting method of four operations.

Addition meaning, subtraction meaning, multiplication meaning, division meaning, addition, subtraction, division, multiplication and check calculation.

Algorithms and simple methods, elementary arithmetic.

Additive commutative law (a+b=b+a), additive associative law (a+(b+c)=(a+b)+c), multiplicative commutative law (a*b=b*a), multiplicative associative law (a*(b*c)=(a*b)*c).

Multiplication distribution law (a*(b+c)=a*b+a*c), continuous reduction property (a-b-c=a-(b+c)) and quotient invariance property A ÷ b = (a× c) ÷ (b× c) = (a ÷.
