The task involves solving addition problems using two methods: a
short way and a
long way. Let's solve each problem step by step.
---
Problem 3: \( 14 + 10 \)
####
Short Way
1. Add the numbers directly:
\[
14 + 10 = 24
\]
####
Long Way
1. Break down the numbers into tens and ones:
\[
14 = 10 + 4
\]
\[
10 = 10 + 0
\]
2. Add the tens and ones separately:
\[
(10 + 10) + (4 + 0) = 20 + 4 = 24
\]
#### Final Answer for Problem 3:
\[
\boxed{24}
\]
---
Problem 4: \( 12 + 15 \)
####
Short Way
1. Add the numbers directly:
\[
12 + 15 = 27
\]
####
Long Way
1. Break down the numbers into tens and ones:
\[
12 = 10 + 2
\]
\[
15 = 10 + 5
\]
2. Add the tens and ones separately:
\[
(10 + 10) + (2 + 5) = 20 + 7 = 27
\]
#### Final Answer for Problem 4:
\[
\boxed{27}
\]
---
Problem 5: \( 4 + 14 \)
####
Short Way
1. Add the numbers directly:
\[
4 + 14 = 18
\]
####
Long Way
1. Break down the numbers into tens and ones:
\[
4 = 0 + 4
\]
\[
14 = 10 + 4
\]
2. Add the tens and ones separately:
\[
(0 + 10) + (4 + 4) = 10 + 8 = 18
\]
#### Final Answer for Problem 5:
\[
\boxed{18}
\]
