9 - 3 x 2=12

Correct answer is 3. Do x then -, not - then x.

200

5 (2x6) + 1= 51

Correct Answer is 61

30  - 6 x 3 = 72

Correct answer is 12

4 + 5 + 7 - 3 x 2 = 26

You need to follow PEMDAS and do x first. Correct answer is 10.

500

10 ³ = 30

10 ³ = 10 x 10 x10, which is 1000, not 30.

Recite the last stanza of "O little town of Bethlehem" from memory

O holy Child of Bethlehem,
descend to us, we pray,
cast out our sin and enter in,
be born in us today.
We hear the Christmas angels
the great glad tidings tell;
O come to us, abide with us,
our Lord Immanuel!
