To find 64-24, you could first find 64-24=40 then what should you do?
Nothing.
64 - 24 = 40
Math - To find 62 - 24, you could first find 64 - 24 = 40. Then what should you ...
If you have already determined that 64 - 24 equals 40, and you would like to proceed further, you could take any number and add 40 to it.
For example, if you take the number 30 and add 40 to it, you would get 70 (30 + 40 = 70).
Alternatively, you could also subtract 40 from any number. Continuing with our previous result, if you take the number 70 and subtract 40 from it, you would get 30 (70 - 40 = 30).
Ultimately, once you have established the value of an arithmetic expression such as 64 - 24, you can perform further operations with the resulting number using addition or subtraction.
