Answer:

11

Explanation:

You can perform the operations in any order, because they are all either addition or subtraction. Use of a number line may help for the 'negative' numbers or subtraction if you're now sure how they combine with multiple additions.
15 - 33 = -18 ; -18 + 29 = 11
Or,
15 + 29 = 44 ; 44 - 33 = 11
Or,
-33 + 29 = -4 ; 15 - 4 = 11

Just another way of thinking about it

Explanation:

We have negative 33

but positive 33 can be split into 15+18

so #-33# is the same as # -15-18#

So write#" "color(green)(15color(red)(-33)+29)# as #color(green)(15color(red)(-15-18)+29)#

#0-18+29#

#29-18 = +11#
