Question

How do you evaluate `65+ 60\cdot 6\div 3- ( 13- 39)`?

Answer 1

`211`

Explanation:

In expressions which involve different operations, always count the number of TERMS first. They are separated by `+ and -` signs.

Each term simplifies to a single answer and these are added or subtracted in the final step.

Within each term, the order is:

• brackets
• powers and roots
• multiply and divide

`" "color(blue)(65)" "color(red)(+60xx6div3)" "color(green)(-(13-39))larr` there are `3` terms
`color(white)(xxxxxxxxx)darrcolor(white)(xxxxxxxx)darr`
`=color(blue)(65)" "color(red)(+360div3)" "color(green)(-(-26))`
`color(white)(xxxxxxxxx)darrcolor(white)(xxxxxx)darr`
`=color(blue)(65)" "color(red)(" "+120)" "color(green)(+" "26)`

`= 185 +26`

`=211`
