My Example

6
Example #1 2 3 x (4+2) + 3 4 =y First do the Parenthesis (4+2) =6 Then the Exponents 2 3 =8, and 3 4 =81 Now the problem is 8 x 6 + 81 = y Multiply 8 x 6 = 48 Then add 48 + 81 y = 129

How to do it on a calculator

8
How to do it on a Calculator 7 3 +(8x9)-45=p First do Parenthesis, (8x9)=72 Next do 7, three times 7x7x7= 343 Next find out the new equation which is 343+72-45=p 343+72=415 415-45=370 p =370
