By following the BODMAS, BIDMAS, PEDMAS rules, we can easily find the values and according to the rules. Division comes first, then multiplication and after then Addition and lastly the subtraction.
As per this question goes; A multiplication of two numbers is provided, so by doing them first: 4 × 3 = 12. After then comes addition. So, 12 + 12 = 24. And finally, the subtraction. So, 24 - 15 = 9. Now, by LaTeX interpreter:
[tex]\mathbf{12 + 4 \times 3 - 15}[/tex]
[tex]\mathbf{12 + 12 - 15}[/tex]
[tex]\mathbf{24 - 15}[/tex]
[tex]\mathbf{9}[/tex]
[tex]\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is: \: 9}}}[/tex]
Hope it helps.
