TIP: With numbers less than 100, add the tens first and then add the units. 16 + 17 = (10 + 10) + (6 + 7) = 20 + 13 = 33
|
TIP: With numbers less than 100, add the tens first and then add the units. 27 + 46 + 83 = (20 + 40 + 80) + (7 + 6 + 3) = 140 + 16 = 156

TIP: With numbers less than 100, add the tens first and then add the units. 3 - 6 + 17 + 28 = (10 + 20) + (7 + 8 + 3) - (6) = 30 + 18 - 6 = 48 - 6 = 42
|
TIP: With numbers less than 100, add the tens first and then add the units. 37 - 19 = (30 - 10) + (7 - 9) = 20 - 2 = 18

TIP: With numbers less than 100, add the tens first and then add the units. (6 + 6 + 6) - 6 = 18 - 6 = 12
|
TIP: With numbers less than 100, add the tens first and then add the units. 25 - 47 + 89 - 5 = (20 + 80 - 40) + (5 + 9 - 7 - 5) = 60 + 2 = 62

TIP: With numbers less than 100, add the tens first and then add the units. 13 + 14 + 36 = (10 + 10 + 30) + (3 + 4 + 6) = 50 + 13 = 63. Don't forget: sometimes you will spot an easy addition which will make the calculation easier, e.g. 14 + 36 = 50
|
TIP: With numbers less than 100, add the tens first and then add the units. 19 - 27 + 56 = (10 + 50 - 20) + (9 + 6 - 7) = 40 + 8 = 48. You could write '19' as '20 - 1' and do the calculation using this. Always BE ON THE LOOKOUT for useful simplifications

TIP: With numbers less than 100, add the tens first and then add the units. 47 - 58 + 19 = (40 + 20 - 50) + (7 - 8 - 1) = 10 - 2 = 8. Here '19' was replaced by '20 - 1' and the calculation was done using using this
|
TIP: With numbers less than 100, add the tens first and then add the units. 0 + 10 + 0 + 28 = (10 + 20) + (8) = 30 + 8 = 38. Ignore zeros!
