query 4.2.20 536 + 279 in expanded notation

Write 536 + 279 in expanded notation.

......!!!!!!!!...................................

RESPONSE -->

537 + 278

(5*10^2) + (3*10^1) + (7*10^0)

+(2*10^2) + (7*10^1) + (8*10^0)

(7*10^2) + (10*10^1) + (15*10^0) which is also

(7*10^2) + (1*10^2) + (1*10^1) + (5*10^0)

(8*10^2) + (1*10^1) + (5*10^0) = 815

** We write this sum as

5 * 10^2 + 3 * 10^1 + 6 * 10^0 +

2 * 10^2 + 7 * 10^1 + 9 * 10^0

______________________________

8 * 10^2 + 10* 10^1 + 15* 10^0. Since 10 * 10^1 = 10^2 we can write this as

9 * 10^2 + 0 * 10^1 + 15 * 10^0.

Since 15 * 10^0 = 10 * 10^0 + 5 * 10^0 = 10^1 + 5 * 10^0 we rewrite this as

9 * 10^2 + 1 * 10^1 + 5 * 10^0.

This result is expressed in our place-value system as

915. **
