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,
\(\Large \color{purple}{\rightarrow 4 - 24(2) \div 4 }\)
\(\Large \color{purple}{\rightarrow 4 - 48 \div 4 }\)
\(\Large \color{purple}{\rightarrow 4 - 12 }\)
\(\Large \color{purple}{\rightarrow -8 }\)
OpenStudy (anonymous):
