700 (seven hundred) is the natural number following 699 and preceding 701. It is the sum of four consecutive primes (167 + 173 + 179 + 181), the perimeter of a Pythagorean triangle (75 + 308 + 317) [ 1 ] and a Harshad number .
The partial differences method is different from other vertical subtraction methods because no borrowing or carrying takes place. In their place, one places plus or minus signs depending on whether the minuend is greater or smaller than the subtrahend. The sum of the partial differences is the total difference. [17] Example:
The plus–minus sign or plus-or-minus sign (±) and the complementary minus-or-plus sign (∓) are symbols with broadly similar multiple meanings. In mathematics , the ± sign generally indicates a choice of exactly two possible values, one of which is obtained through addition and the other through subtraction .
The plus sign (+) and the minus sign (−) are mathematical symbols used to denote positive and negative functions, respectively. In addition, + represents the operation of addition , which results in a sum , while − represents subtraction , resulting in a difference . [ 1 ]
Raising the decimal digits of 175 to the powers of successive integers produces 175 back again: 175 = 1 1 + 7 2 + 5 3. [1] 175 is a figurate number for a rhombic dodecahedron, the difference of two consecutive fourth powers: 175 = 4 4 − 3 4. [2] It is also a decagonal number and a decagonal pyramid number, the smallest number after 1 that has ...

In mathematics, −1 (negative one or minus one) is the additive inverse of 1, that is, the number that when added to 1 gives the additive identity element, 0. It is the negative integer greater than negative two (−2) and less than 0 .
170 is the smallest n for which φ(n) and σ(n) are both square (64 and 324 respectively).But 170 is never a solution for φ(x), making it a nontotient.Nor is it ever a solution to x - φ(x), making it a noncototient.
