13.425

first you have to do whats in the parenthesis and then what ever answer you get you multiply it by whats outside of the parenthesis

#-2.5 (3.7 - 9.07)#

#=> -2.5 (-(9.07-3.7))#

#=> -2.5(-5.37)# as #9.07 - 3.7 = 5.37#

#=> -2.5 * - 5.37# Removing the bracket

#=> 2.5 * 5.37# as #(-) * (-) = +#

#=> 13.425#
