Question

How do you find `25\div 5+ 6\times ( 12- 4)`?

Answer 1

`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`
