Question

Mr Kendrick made three deposits to his account in order 460 185 and 240 show how to use commutative property on the sum of deposit mentally

Answer 1

Commutative property: when you have to solve a sum, it does not matter the order in which you place your addends, since you will always get the same result.
 We have then:
 ((40) + (185)) + (240) = 465
 (240) + ((40) + (185)) = 465
 answer:
 Form 1:
 ((40) + (185)) + (240) = 465
 Form 2:
 (240) + ((40) + (185)) = 465
