#25div5+6xx(12-4)#

#=53#

Explanation:

In a calculation which has different operations, count the number of terms first. They are separated by plus and minus signs.

Within each term, the order is:

  • brackets,
  • powers and roots
  • multiply and divide

Simplify each term to a single value and these are added and subtracted in the final step.

#" "color(red)(25div5)" "color(blue)(+6xx(12-4))" "larr# there are two terms
#color(white)(xxxx)darrcolor(white)(xxxxxxxx)darr#
#=" "color(red)(5)" "color(blue)(+" "6xx(8))#

#=" "color(red)(5)" "color(blue)(+" "48)#

#= 53#
