Multiplicative commutative law: a×b=b×a

Law of multiplicative association: (a×b)×c=a×(b×c)

Additive commutative law: A+B = B+A.

Additive associative law: a+b+c=(a+b)+c=a+(b+c)

The law of multiplication and distribution is the sum of two numbers multiplied by one number. You can multiply them by this number first and then add them up. Generally, in rational number multiplication, multiplying a number by the sum of two numbers is equivalent to multiplying this number by these two numbers respectively, and then adding the products.

Multiplication and division can also be used to calculate decimals and fractions: the reverse application of multiplication and division.

Reverse application of multiplication and distribution law;

35×37+65×37

=37×(35+65)

=37× 100

=3700
