Parth (parthkohli):

OpenStudy (anonymous):

there is (7-5)in the brackets...it will give 2.... that will give 4-24(2)=-44...dividing by 4 will give _11

Parth (parthkohli):

No, \(\Large \color{purple}{\rightarrow 4 - 24(2) \div 4 }\) \(\Large \color{purple}{\rightarrow 4 - 48 \div 4 }\) \(\Large \color{purple}{\rightarrow 4 - 12 }\) \(\Large \color{purple}{\rightarrow -8 }\)
