Let's solve each of the given mathematical expressions step-by-step to find the largest number:
1. First Expression:
[tex]\[ 200 + 520 \][/tex]
Adding 200 and 520, we get:
[tex]\[ 200 + 520 = 720 \][/tex]
2. Second Expression:
[tex]\[ 452 - 102 \][/tex]
Subtracting 102 from 452, we get:
[tex]\[ 452 - 102 = 350 \][/tex]
3. Third Expression:
[tex]\[ 222 / 2 \][/tex]
We divide 222 by 2 to get:
[tex]\[ 222 / 2 = 111.0 \][/tex]
4. Fourth Expression:
[tex]\[ 15 \times 15 \times 2 \][/tex]
First, we multiply 15 and 15:
[tex]\[ 15 \times 15 = 225 \][/tex]
Then we multiply the result by 2:
[tex]\[ 225 \times 2 = 450 \][/tex]
Now we have the results for each of the expressions:
1. [tex]\( 200 + 520 = 720 \)[/tex]
2. [tex]\( 452 - 102 = 350 \)[/tex]
3. [tex]\( 222 / 2 = 111.0 \)[/tex]
4. [tex]\( 15 \times 15 \times 2 = 450 \)[/tex]
Among these results, the largest number is [tex]\(720\)[/tex].
