The number of partial products Alan will have when he multiplies a 4-digit number by 36 is; 8 partial products.
First, we must establish that a 4-digit number will have 4 place values namely;
- Thousands
- Hundreds
- Tens
- Ones.
And since, 36 has 2 place values;
We can conclude that the number of partial products that Alan wil have is; 2× 4 = 8.

57-36=21 times (rolled less than 3)
36:21 →12:7
Step-by-step explanation:
7^2+8^2=113
Then square root 113 which is 10.63 to 2.d.p
So x=10.63
Answer:
1. 125
2. 25
3. 40
4. 39
First question:
(15-10)^2 + (15-5)^2
parentheses first to get 5^2 + (15-5)^2
exponents next to get 25 + (15-5)^2
parentheses again 25 + 10^2
exponents again 25 + 100 = 125
Second question:
simplify the exponents (3 *3) + (4 * 4) + (2 * 2) to get 9 + 16 + 4 = 29
Third question:
simplify in the parentheses 6 1/7 - 1/7 = 6
divide 60 by 6 to get 10
multiply 10 by 4 to get 40!
Fourth question:
simplify the fractions to get 1/3 + 8/3 = 3
multiply the 3 by 13 to get 39
