Write the number equal to 5 tens and 13 ones

serious [3.7K]

To find this out we have to add 5 tens and 13 ones.
5 tens is equal to
10 + 10 + 10 + 10 + 10 = 50

And 13 ones is equal to
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 13

Now add 50 and 13
50 + 13 = 63

So your answer is 63

good Luck! :)
