1. Evaluate the expression $9^2 + 1 -7*(8+4)/2$
``` P - add 8 + 4
New expression is 9^2 + 1 - 7 * 12 / 2
E - solve the exponents
New expression is 81 + 1 - 7 * 12 / 2
M - multiply 7 * 12
New expression is 81 + 1 - 84 /2
D - Divide 84 /2
New expression is 81 + 1 -42
A - Add 81 + 1
New Expression is 82 - 42
S - Subtract 82-42
Final expression is 40
