The order is - First bracket then division then multiplication then summation and last subtraction.
Qt A
\((6 + 3) × 5 – 6 ÷ 2 + 3\)
\((6 + 3) × 5 – 3 + 3\)
\((9) × 5 – 3 + 3\)
\(45 - 6 = 39\)
Qt B
\(6 + 3 × 5 – 6 ÷ 2 + 3^2 \)
\(6 + 3 × 5 - 3 + 9\)
\(6 + 15 - 12\)
\(21 - 12 = 9\)
Answer A
Qt A
\((6 + 3) × 5 – 6 ÷ 2 + 3\)

Answer A
Hi, Thank you for sharing answer.
Just confirmation, I think you missed the calculation of A), you did add 3 in last, but it should be 9,3^2, I think.
Also, for B), I think , -3 + 9 should be +6 , not -12.
It does not change the conclusion, though.
