Final answer:
In mathematics, an equation is a mathematical formula that expresses the equality of two expressions connected by an equal sign. To find three different addition equations that have the sum of 834 and require at least one new group, you can use different number combinations.
Step-by-step explanation:
To find three different addition equations that have the sum of 834 and require at least one new group, we can use different number combinations. Here are three examples:
In each equation, when you add the two numbers together, the sum is 834. These equations require forming new groups of numbers to get the desired sum.
