How much is 1 60 added together?
The sum of the first 60 integers is 1,830. Rather than starting at 1 and counting and adding up all of the integers to 60, we can use Gauss’ formula….
What is a 6 digit number between 1 to 9 and it to give the sum 20 without repeating any number?
With that set (1-9) to choose from, the smallest even sum of six digits is 2+3+4+5+6+8=28. You need to include 0 in the set of available digits to get six digits which sum to 20 without repeating any. THEN, the answer would be 6+5+4+3+2+0.
What two numbers add up to 20?
1 Expert Answer 13 and 7, one has the answer: 13+7 equals 20 and has a difference of 6.
Why do we get two different answers to the same expression?
Without an agreed upon order of when we perform each of these operations to calculate a written expression, we could get two different answers.
What are the 4 rules of algebraic expression?
The four rules below are enough for most purposes: RULE 1: Calculate anything in brackets first, then apply the other rules. (For further discussion about expressions with more than one set of brackets, see the next section.) RULE 3: If a calculation involves only multiplication and division, work from left to right.
How do you create every number from 1 to 50?
Your task is to create every number from 1 to 50. You can use only the numbers 1, 2, 3 and 4 once in each and the operations + – x / . You can use the numbers as powers, and you must use all of the numbers 1, 2, 3, 4. Here are some examples:
Do we work out 4 + 5 first then multiply by 3?
We do NOT work out 4 + 5 first to get 9 and then multiply by 3. Example of Rule 1: (4 + 5) x 3 (4 + 5) x 3 is equal to 27, because we calculate the brackets first to 4 + 5 = 9 and then multiply by 3. We do NOT work out 5 x 3 and then add 4.
