4 + 1 - 2 = 3
No, the numbers 1,1+2, 1+2+3, 1+2+3+4, 1+2+3+4+5... are triangular numbers.
1 x 1 = 1 2 x 2 = 4 4 - 1 = 3 Answer: the numbers are 1 and 2
4 x (3 + 2) - 1.
It is: 2*(3+4)+1 = 15
If the digits are repeatable, the answer is 4*4*4*4. If the numbers cannot be repeated, then it is 4*3*2*1.
Proof: First, we conduct prime numbers. 1=2-1 2 3=4-1 4 5=2-3*(-1) 7=4-3*(-1) 11=4*2-3*(-1) 13=4*(-3)+2-1 Then 6=32=(4-1)2 8=4*2 9=(-3)2 10=2*5=2*2-3*(-1) 12=3*4 14=7*2 15=5*3 16=8*2 31 =42*2-1
To add mixed numbers with like denominators, first add the whole numbers, then add the fractions. For example: 2 2/3 + 4 1/3 = ?? First add the whole numbers. 2 2/3 + 4 1/3 = 6? Then add the fractions. 2 2/3 + 4 1/3 = 6 3/3 Simplify. 3/3 is one. 2 2/3 + 4 1/3 = 6 + 1 = 7.
32 + 1 - 4 or 4! + (3 x 2) -1 or 1(4! + 3 + 2) equal 29.
(4 + 1) x 3 + 2.
The prime numbers from 1 to 4 are 2 and 3.
the answer is 3
