What would you solve second?
30÷(2×3)+18
divide 30 by 6

Players earn (25 points for each win) and lose 6 points for each loss.
Jordan has 3 wins and 4 losses, and Mia has 2 wins and 1 loss.
How many more points does Jordan have than Mia?
Jordan: 3×25−4×63 \times 25 - 4 \times 63×25−4×6
Mia: 2×25−1×62 \times 25 - 1 \times 62×25−1×6
Jordan − Mia = 51 − 44 = 7

A school is buying equipment for intramurals.
They order 4 sets of gear, and each set includes (3 soccer balls and 5 basketballs).
A soccer ball costs $18, and a basketball costs $22.
Then, the school applies a $50 discount to the total order.
How much do they spend after the discount?

The problem was 20 - 5 x 2 + 3. My answer was 33. What did I do wrong?
I did not multiply first. The answer should be 13.
A music store is creating prize packs.
Each prize pack includes 4 guitar picks at $3 each and 2 mini drumsticks at $12 each.
