Please. Someone help me
4. The sequence of calculation
a) 3+ 4-7
b) 7 * 36 = 252
c) 252 - 5 = 247
can be replaced by
(3+4) 36-5-247.
By proceeding as above, express each
sequence of operations by one equality:
a) 3 + 8 = 11 : 11* 10 = 110
b) 3X 6 = 18 : 18x 40 = 720
c) 4x 80 = 320 : 320 - 12 = 308 :
308 + 34 = 342
d) 5x 70 = 350 ; 40 + 12 = 52 ;
350 - 52 = 298
