Describe a way to calculate 304-81 mentally by using reasoning other that the common subtraction algorithm. Then write a coheren
Leno4ka [110]

Answer:

A simple way to mentally subtract is to simplify the numbers, subtract, then subtract or add for the simplified answer.

Step-by-step explanation:

A simple way to mentally subtract is to simplify the numbers, subtract, then subtract or add for the simplified answer. For this 304 - 81 is easier as 300 - 80. Make note that we took away 4 from 304 and 1 from 81. Now we just subtract mentally, and 300 - 80 = 220. If we took 4 from 304, this means that our answer should be 4 less, since 4 less would be 304 - 80 = 216. If we took 1 from 81, then we add 1 back to get the equation 304 - 81 = 217.

304 - 81 = ?

300 - 80 = 220

304 - 80 = 216

304 - 81 = 217
