Answer 1

Step-by-step explanation:

• it's not communicative property
• it's commutative property i think
• rule a+b=b+a
• -145+623=623+(-145)
• 145=145
• thus above numbers obey commutative property

Answer 2

Answer:

First of all the property is commutative property not communicative which tells us that order doesn't matter in the case of addition and multiplication.

-145+623=623+(-145)=478

-145×623=623×(-145)=-90,335
