A. J. Lohwater's Russian-English Dictionary of the Mathematical Sciences

past	повёз, повезла, повезло, повезли
Note the past tense of везти and повезти.

Furthermore, these verbs of going and carrying may be prefixed by 'directional prefixes.' For example, the verb приносить/принести means 'to bring'; the verb уносить/унести means 'to carry away,' or 'to take away.' The prefix при- means 'up to,' while у- means 'away.' These prefixed compounds have only two forms: imperfective and perfective.

Footnotes

1.	Note that in the past tense forms, gender is distinguished in the singular, but not in the plural. The endings are the zero-ending for masculine subjects, -а for feminine subjects, - о for neuter subjects, and -и for plural subjects. These endings, preceded by the past tense suffix -л-, are added to the verbal stem, which is usually formed by removing the infinitival suffix -ть. This is true for the past tense forms of most verbs. Example: решить — решил (m.), решила (f.), решили (pl.). ^
2.	These forms are archaic but do appear. ^
3.	These endings are 'nonpast' endings; they are used for the imperfective present tense as well as the perfective future. ^
4.	This verb is reflexive; the suffix -ся in no way interferes with the conjugation of the verb — it is merely attached to the end of the conjugated verb. ^
5.	Note the loss of the stem-final consonant in deriving the infinitive. ^
6.	Note, however, that in form, the endings of the perfective future are the same as those of the imperfective present tense. Therefore, care must be taken to determine whether the verb is perfective or imperfective. ^
7.	Note the loss of stem-final vowel in forming this participle. ^

Some Comments on the Translation of Verb Forms

The difference in the sense of the imperfective and perfective can be emphasized by exhibiting both aspects of the same verb in one sentence. (It is recommended that each word in the sentence be looked up in the dictionary; the superscripts refer to the comments immediately following the translation.)

Прежде чем¹ доказывать,² что все собственные значения матрицы A удовлетворяют³ уравнению (4), мы докажем,⁴ что если h(?) — общий наибольший делитель⁵ элементов присоединённой к A – ?I матрицы,⁶ то⁷ ?(?) = h(?)?(?).

Before we go on to prove (or, Before we prove) that all the eigenvalues of the matrix A satisfy equation (4), we shall prove that if h(?) is the highest common divisor of the elements of the matrix (which is) adjoint to A – ?I, then ?(?) = h(?)?(?).

Notes

1.	Under the entry прежде appears the phrase прежде чем as a conjunction, meaning before, which is usually followed by an infinitive. ^
