Commutative and Associative Properties

The commutative law applies to addition and multiplication. Division and subtraction do not follow this law.

Using the commutative law, first add $35+55=90$. Then add $60+90=150$, making the calculation easier.

Start by calculating $25\times 4=100$. Then multiply $48\times 100=4800$.

Start by adding $36+100=136$. Then add $136+64=200$.

Adding the numbers step by step gives $50+225=275$, and then $275+175=450$.

Using step-by-step multiplication: $250\times 3=750$, then $750\times 4=3000$, and finally $3000\times 2=6000$.
