Yes! When adding 5, think of it as adding 10 and subtracting 5. For 55: add 10 to get 65, then subtract 5 to get 60. This works great for mental math!
65 would be the answer if we added 10 to 55. But we're only adding 5, so: 55 + 5 = 60, not 65. Always check that you're using the right numbers!
Work out the problem before looking at the choices! Calculate 55 + 5 = 60 first, then find 60 among the options. This prevents you from picking a tempting wrong answer.
