Let's solve each of these simple addition problems step by step:
(a) 54 + 25
To add these numbers, start with the rightmost digits (the ones place). Add $4 + 5 = 9 . Then, add the digits in the tens place: $5 + 2 = 7 . So, 54 + 25 = 79 .
(b) 35 + 35
Add the ones place: $5 + 5 = 10 . Write $0 and carry over $1 to the tens place. Add the tens place, including the carried-over $1 : $3 + 3 + 1 = 7 . So, $35 + 35 = 70 .
(c) 45 + 46
Add the ones place: $5 + 6 = 11 . Write $1 and carry over $1 to the tens place. Add the tens place, including the carried $1 : $4 + 4 + 1 = 9 . So, $45 + 46 = 91 .
(d) 56 + 23
Add the ones place: $6 + 3 = 9 . Add the tens place: $5 + 2 = 7 . So, 56 + 23 = 79 .
(e) 14 + 13
Add the ones place: $4 + 3 = 7 . Add the tens place: $1 + 1 = 2 . So, 14 + 13 = 27 .
(f) 29 + 15
Add the ones place: $9 + 5 = 14 . Write $4 and carry over $1 to the tens place. Add the tens place, including the carried $1 : $2 + 1 + 1 = 4 . So, $29 + 15 = 44 .
(g) 17 + 2
Add the ones place: $7 + 2 = 9 . The tens place stays the same: $1 . So, 17 + 2 = 19 .
(h) 13 + 29
Add the ones place: $3 + 9 = 12 . Write $2 and carry over $1 to the tens place. Add the tens place, including the carried $1 : $1 + 2 + 1 = 4 . So, $13 + 29 = 42 .
(i) 56 + 33
Add the ones place: $6 + 3 = 9 . Add the tens place: $5 + 3 = 8 . So, 56 + 33 = 89 .
(j) 40 + 39
Add the ones place: $0 + 9 = 9 . Add the tens place: $4 + 3 = 7 . So, 40 + 39 = 79 .
(k) 29 + 13
Add the ones place: $9 + 3 = 12 . Write $2 and carry over $1 to the tens place. Add the tens place, including the carried $1 : $2 + 1 + 1 = 4 . So, $29 + 13 = 42 .
(l) 59 + 20
Add the ones place: $9 + 0 = 9 . Add the tens place: $5 + 2 = 7 . So, 59 + 20 = 79 .
(m) 49 + 16
Add the ones place: $9 + 6 = 15 . Write $5 and carry over $1 to the tens place. Add the tens place, including the carried $1 : $4 + 1 + 1 = 6 . So, $49 + 16 = 65 .
These exercises help practice basic addition, which is an essential skill in mathematics. If there's anything specific you'd like help with, feel free to ask!
