First you had to apply rule.
[tex]12*23[/tex]
Then you multiply by the numbers.
[tex]12*23=276[/tex]
Final answer: [tex]\boxed{=276}[/tex]
[tex]276/23=12[/tex]
[tex]276/12=23[/tex]
[tex]23*12=276[/tex]
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
