# Sicp Exercise 1.3

sicp

Exercise from SICP:

Define a function that takes three numbers as arguments and returns the sum of the two larger numbers.

# Solution

The first thing we need to do is to get the largest two numbers from 3 numbers. We can do this with a conditional statement.

```
(define (sum-square-largest-two a b c)
(cond ((and (<= a b) (<= a c)) (sum-of-squares b c))
((and (<= b a) (<= b c)) (sum-of-squares a c))
((and (<= c a) (<= c b)) (sum-of-squares a b))))
```
