To solve this question, let's say the unknown values are x.

Part 01:

[tex]x+0=3[/tex]

To solve it, you can use the Identity property.

According to this property, adding 0 to a number does not change the number.

So,

[tex]\begin{gathered} x=3 \\ 3+0=3 \end{gathered}[/tex]

Part 02:

[tex]9+2=2+x[/tex]

To solve it, you can use the Commutative Property.

According to this property, changing the order of addends does not change the result.

[tex]\begin{gathered} x=9 \\ 9+2=2+9 \end{gathered}[/tex]

Part 03:

[tex]3+(5+6)=(3+5)+x[/tex]

To solve it, you can use the Associative Property.

According to this property, you can change the grouping of the addends without changing the result.

[tex]\begin{gathered} x=6 \\ 3+(5+6)=(3+5)+6 \end{gathered}[/tex]
