(8 - 6363 : 909) + 321 * 11 + 123 * 10 = 4762
1) 6363 : 909 = 7
2) 8 - 7 = 1
3) 321 * 11 = 3531
4) 123 * 10 = 1230
5) 1 + 3531 + 1230 = 4762
<u>252</u> + 12 = <u>264</u> + 12 = <u>276</u> + 12 = <u>288</u> + 12 = <u>300</u> + 12 = <u>312</u> + 12 = <u>324</u> + 12 = <u>336</u> + 12 = <u>348</u> + 12 = <u>360</u>
