.
So, number of tulips that can be bought with the above amount can be obtained by substituting for cost. This gives,
.

P = 2 (l + w)
P = 2(6 + 1)
P = 2 x 7
P = 14

First look at the Brackets
There are no indices in the brackets
There is no division in the brackets
There is a Multiplication in the brackets 7 x 3
For the answer
(9 - 7 x 3 + 4)²
Brackets
Multiplication 7 x 3 = 21
(9 - 21 + 4)²
Addition -21 + 4 = -17
(9 - 17)²
Subtraction 9 - 17 = -8
-8²
Now start again once the brackets are gone
-8²
Indices
-8 x -8 = 64
