The method includes receiving a sequence of inputs on a computing device. The sequence of inputs specifies the technical formula. The method also includes displaying the technical formula in response to receiving the sequence of inputs. Additionally, the method includes determining an alternate sequence of inputs that specify the technical formula. The alternate sequence of inputs may be input to the computing device to display the technical formula. The method further includes displaying the alternate sequence. ## Claims ### Claim 1 A method for entering a technical formula, comprising: receiving a sequence of inputs on a computing device, wherein the sequence of inputs specifies the technical formula; displaying the technical formula in response to receiving the sequence of inputs; determining an alternate sequence of inputs that specify the technical formula based on the sequence of inputs received, and, which may be input to the computing device to display the technical formula; and displaying the alternate sequence, wherein an equivalent alternate input is highlighted within the display as an input is received from the sequence of inputs as feedback, the equivalent alternate input being associated with a different input modality than an input modality of the sequence of inputs received. ### Claim 2 (depends on 1) The method recited in claim 1, wherein a plurality of alternate input sequences specifies the technical formula in a corresponding plurality of input modalities. ### Claim 3 (depends on 2) The method recited in claim 2, wherein the plurality of input modalities comprises: handwriting;

text message; chat message; social networking communication; and a cache storage at a client of a user entering the sequence of inputs. ### Claim 13 (depends on 1) The method recited in claim 1, comprising: receiving a first part of the technical formula entered in a first input modality; and receiving a second part of the technical formula entered in a second input modality. ### Claim 14 (depends on 1) The method recited in claim 1, comprising receiving one or more parts of the technical formula, wherein each of the one or more parts is entered in one or more input modalities. ### Claim 15 A system for entering a technical formula, comprising: a processing unit; and a system memory, wherein the system memory comprises code configured to direct the processing unit to: receive a sequence of inputs on a computing device, wherein the sequence of inputs specifies a first part of a technical formula; determine a second part of the technical formula based on the sequence of inputs; display the second part of the technical formula based on the first part; determine an alternate sequence of inputs that specify the technical formula based on the sequence of inputs received, and, which may be input to the computing device to display the technical formula; and present the alternate sequence, wherein an equivalent alternate input is highlighted within the display as an input is received from the sequence of inputs as feedback, the equivalent alternate input being associated with a different input modality than an input modality of the sequence of inputs received. ### Claim 16 (depends on 15) The system recited in claim 15, wherein the code configured to determine the second part of the technical formula comprises code configured to direct the processing unit to: determine an expression for the sequence of inputs; and determine a production rule for the expression. ### Claim 17 (depends on 15) The system recited in claim 15, comprising code configured to direct the processing unit to: receive the first part of the technical formula entered in one or more input modalities; and receive the second part of the technical formula entered in one or more input modalities. ### Claim 18 (depends on 15) The system recited in claim 15, wherein the alternate sequence of inputs is presented: as a display on the computing device; as audio from the computing device; or combinations thereof. ### Claim 19 (depends on 15) The system recited in claim 15, wherein a plurality of alternate input sequences specify the technical formula in a corresponding plurality of input modalities. ### Claim 20 One or more computer-readable storage media, comprising code configured to direct a processing unit to: receive a sequence of inputs on a computing device, wherein the sequence of inputs specify a technical formula comprising a first part entered in a first input modality and a second part entered in a second input modality;
