EQUATION: 5(3+4)-{8-(9+6)]} MY WORK: = 5(7)-{8-[5-(9+6)]} = 35-{8-[5-(9+6)]} = 35-{8-[15]} = 35-{8-[-10]} = 35- {8+10} = 35-18 = 17

okay...thank you bob :)

MATH
EQUATION: (NOTE: THIS IS A FRACTION) 5-(-2^3)(2)/6xsqrt9 -9x2 MY ANSWER: = 5-(-8)(2)/6x3-9x2 = 5+8(2)/18-9x2 = 5+16/18-18 = 21/0 = undefined
