Multiplying
 

When simplifying an expression involving multiplying and dividing it can often be helpful to write out the expression in full first.

Remember when multiplying the order doesn't matter.

  • a2 × a3 = a × a × a × a × a = a5
     
  • 3a2 × a = 3 × a × a × a = 3a3
     
  • 2x2 × 5x = 2 × x × x × 5 × x = 10x3
