XXXXX is X*6= XX, XX*X= 52 in XXX below XXXX
X+[12-{8+X-(XX+1-52)}]
in the XXXX XXXX XX XXXX for "D" in XXXXXX which XX divison XXXXXXX inside brackets, XXXXX XXXXX are no division, XXXXXXXX XXXX XXXX which is "M" XXXXX is XXXXXX XXX XXX XXXXXXXXXXXXX brackets, so next XX "A" XXXXX is additions XX solve itpresent XXXXXX XXXXXXXX, XXXXX is XX+1= XX , in XXX below step
7+[12-{X+X-(55-XX)}]
in the next order XX XXXXXX XXXX for "S" in XXXXXX which is XXXXXXXXXXXXXXXXXX XXXXXX XXXXXXXX, which XX XX-52, XXXXX as in next XXXX
X+[XX-{8+X-(X)}]
now eliminating XXX XXXXXXXX again , XXX next XXXXX+[XX-{8+3-3}]
so again XXXX XXX XXXXXX, XXXXX there XX no divison and XXXXXXXXXXXXXX ,XXXX XX "X" which XX additions XX solve XXXXXXXXX inside brackets, which is X+3=11
X+[XX-{XX-X}]
so XXXXX look XXX BODMAS, XXXXX XXXXX is XX divison andmultiplication XXX XXXXXXXX in the brackets, so XXXXX XXX "S" subtraction, which XX XX-X=X, XX show below
7+[XX-X]
now again solve,look XXX XXXXXX, XXXXX XXXXX is no divison XXXXXXXXXXXXXXXXX XXX addition in XXX XXXXXXXX, so XXXXX for "S" subtraction, which is 12-8=4, as shown XXXXX
7+4
now addXX
so XXX answer XX XX
