#29.86+7 -5.73#

=#31.13#

#29.86-5.73+7#

Re-arrange the expression with all the additions at the front to be done first.

#29.86+7 -5.73#

=#31.13#

CBe careful with just applying BODMAS or PEDMAS .. where the addition has to be done before the subtraction!

The addition is NOT #5.73 +7#!!!!!!

The additions are #+29.86 and +7# while the subtraction is just: #-5.73#

If you were supposed to add #5.73 +7# first, the expression would be:

#29.86-(5.73+7)#

Without brackets, the correct answer comes from:

#29.86+7 -5.73#
