Question

Математика 2 вариант 230×320+230×68 38×5800+380×520 84×670-640×67 нам учитель написал куда-то 0 прибавлять , а я не поняла

Answer 1

230×320+230×68=230*(320+68)=230 *388=89240
38×5800+380×520=380×580+380×520=380* (580+520)= 380*1100=418000
84×670-640×67=840*67-640*67=67*( 840-640)=67*200=13400

Answer 2

Solving the Math Problem

To solve the given math problem, let's break it down step by step:

1. Calculate 230×320: - 230×320 = 73600

2. Calculate 230×68: - 230×68 = 15640

3. Calculate 38×5800: - 38×5800 = 220400

4. Calculate 380×520: - 380×520 = 197600

5. Calculate 84×670: - 84×670 = 56280

6. Calculate 640×67: - 640×67 = 42880

Now, let's add all these results together and then add 0 to the sum as per the instruction.

Sum of the products: 73600 + 15640 + 220400 + 197600 + 56280 - 42880 = 504640

Finally, adding 0 to the sum: 504640 + 0 = 504640

So, the final result after adding 0 is 504640.
