How Much More? 🤔
You have some money, but not enough yet. How much MORE do you need? 🧮
Subtraction to the rescue! ➖
Subtracting Numbers ➖
Use the - sign to take away.
print(10 - 4)Goal Minus Saved 📉
To find what's left, subtract saved from goal!
goal = 30
saved = 12
print(goal - saved)The Difference 🔢
That answer is called the difference. Save it in a box!
goal = 30
saved = 12
left = goal - saved
print('You need', left, 'more')A Friendly Message 😊
Tell the saver exactly how much is left!
left = 18
print('Save', left, 'more to win! 🎉')What If You Have Enough? ✅
Use if so you don't show a number when you already reached the goal!
goal = 30
saved = 35
if saved >= goal:
print('All done! 🥳')
else:
print('Need', goal - saved, 'more')Not Enough Yet 💪
Try it when you still need to save more.
goal = 50
saved = 20
if saved >= goal:
print('Done!')
else:
print('Need', goal - saved, 'more 💪')Show With $ 💲
Add a dollar sign to the amount left.
left = 18
print('Still need: $' + str(left))Halfway There? ➗
Are you halfway? Compare saved to half the goal!
goal = 30
saved = 18
if saved >= goal / 2:
print('Over halfway! 🌟')Days to Go 📅
If you save 3 each day, how many days until your goal? Use // for whole days!
left = 18
per_day = 3
print('Days left:', left // per_day)Big Goal 🏔️
Try a bigger goal and see how much more you need!
goal = 100
saved = 65
print('Need', goal - saved, 'more!')Quick Check ✅
