If PQ and RS are two 2-digit numbers, then
PQ * RS = 100*P*R + 10*P*S + 10*Q*R + Q*S

Here is how to multiply using the distributive property:First, the equation: 9 (x + 3) = 35There must be parentheses for the distributive property, and a number outside those parentheses. The next step is to multiply 9 by x and 9 by 3 individually, and put an addition symbol in the middle.The second equation: 9x + 27 = 35Then, subtract 27: 9x = 18Divide by 9 on both sides: x = 2.That is how you multiply using the distributive property.

You need the associative and commutative properties, but not the distributive property. n*4n*9 =n*(4n*9) (associative) = n*(9*4n) (commutative) = n*(36n) (associative) = 36n*n commutative = 36*n^2
