I try to think of numbers that are
around 1945 when you square them.
too high
too low
too high
just right
That would make Bruce 9 years old
( depending on the month he was born )
In 1988 on his birthday, Bruce would
be exactly

Number of legs =
given:

This is 1 equation with 2 unknowns, so it

Subtract from both sides

Add to both sides

What if there are 10 cows?

What if there are 11 cows?

What if there are 12 cows?

There can't be minus one turkey, so
the largest possible number of cows
is 11
check answer:

Subtract from both sides

That's correct
