−10−3−5×3= -10-3-5\times3= −10−3−5×3=
According to the order of operations, we first place the multiplication exercise in parentheses:
−10−3−(5×3)= -10-3-(5\times3)= −10−3−(5×3)=
We solve the multiplication exercise:
5×3=15 5\times3=15 5×3=15
Now we obtain the exercise:
−10−3−15= -10-3-15= −10−3−15=
We solve the exercise from left to right:
−10−3=−13 -10-3=-13 −10−3=−13
−13−15=−28 -13-15=-28 −13−15=−28
−28 -28 −28
