Add Units Problem: Calculate 44 + 30 Step by Step

Q: Why do we line up the numbers when adding?

Place value matters! Each digit position represents a different value (ones, tens, hundreds). When we line up numbers, we make sure we're adding ones to ones and tens to tens.

Q: Can I add these numbers in my head?

Absolutely! For $ 44 + 30 $, you can think: '44 plus 30 is 44 plus 3 tens, which is 74'. Mental math is great when you understand place value!

Q: What if I get confused about which number to add first?

Addition is commutative, meaning $ 44 + 30 $ gives the same result as $ 30 + 44 $. Start with whichever feels easier!

Q: How can I check my answer without using a calculator?

Try counting by tens from 44: 54, 64, 74. Or use subtraction to check: $ 74 - 30 = 44 $ ✓

Q: Why is this called 'adding thirty units'?

The word 'units' just means individual counting numbers. So 'thirty units' is the same as saying 'thirty' or $ 30 $.
